Write an equation of a line that is perpendicular to the given line and has the same y–intercept. A coordinate graph can help graph functions which is an equation using a variable to define the other. A linear function is a first degree equation of two variables x and y where x is the independent variable and y is the dependent variable. Note: The intercepts of a linear function (or any function) are officially coordinate pairs, and teachers will expect them this way!
Even though the slope or intercepts are not obvious in standard form, an equation in this form is still able to be graphed easily. To put a graph of a line into standard form, it is best to put the line into slope intercept form first.
These topics include graphing linear equations and inequalities and observing linear models. A plane is like a universe in two spacial dimensions rather than our universe of three spacial dimensions.
In other, simpler words, a linear function is an equation that forms a line on a coordinate plane.
A positive slope is characterizes by a line emerging from the lower left part of the graph and exiting off the upper right. This equation is solved for y meaning the value of y can be calculated arithmetically with any value of x. Immediately, you know one of the points, and with the slope, you can find a new one like in the previous form.
A graph only needs two points to be graphed, and the intercepts of an equation can be easily found.
The plane is divided into four Quadrants by the axes which are characterized by the sign of the units of its (x,y) pairs.


Each equation uses the variables x and y which represent the location on the axes of a graph. This form directly exposes the slope and y-intercept which is all you need in order to graph an equation. As you should know, to find the x-intercept, substitute 0 for y, and to find the y-intercept, substitute 0 for x.
Simply, Quadrant I will only contain points with (+,+) pairs, Quadrant II will have (-,+) points, Quadrant III will contain (-,-) points, and Quadrant IV has (+,-) points. A negative slope is the opposite of a positive slope where it enters from the top left corner and exits the bottom right.
The intercepts of a line help characterize a linear function, and in the real world an intercept can represent where payments are over or minimum cost for something. The form incorporates the slope and room for a point which can easily be algebraically solved into Slope-intercept form. When the variables have been filled in, you can algebraically solve for y to put the equation in slope-intercept form or solve for the standard form (which comes next).
So, the general description of a Standard linear equation is the sum of the integer amounts of x's and y's to equal an integer constant. For example, in the equation y=2x, 2 is the rate by which y increases or decreases depending on the value of x. In standard form, the slope and intercepts are not obvious, and if you want to identify slope, putting the equation into slope intercept form.
At this time, remove all fractions and decimals by multiplying the equation by the appropriate numbers, presumably the denominator of the fractions.
Every mark on this graph is one unit apart; some coordinate graphs have dilated axes which means that the marks are either less than or greater than one unit apart. One you have the y-intercept and another point or just two points, use your slope formula to find the slope m.


In this case, there is no rate of change meaning that no matter what the value of x is, y is the same.
For any slope, translate up the amount of the numerator (if negative, you must go down) and translate right the amount of the denominator (if negative, go left).
Now, we will describe each form in detail including the way how to use the equation to graph a line and using a line to produce an equation. Since the form uses subtraction, the point numbers in the equation are the opposite of what they actually are. The point-slope form is very useful in problems that give you the slope of a line and a point.
This means that it is 6 units in the positive horizontal direction (right) and 3 units in the positive vertical direction (up). A vertical line parallel to the y-axis has an undefined slope since division by zero must take place. If not, plug the x and y components of one of the two points into the form along with the slope and solve algebraically for b. In our previous example, we found the slope using a special equation and the two intercepts. These can be the intercepts, but for this example, we will use the x-intercept, (4,0), and another point on the line, (8,-3).
