How to graph Use the slope-intercept form to graph the equation - 5x + y = - 4.

Step-by-step explanation:

1. Turn the equation into its correct format. The slope-intercept form is equal to y=mx+b.

(In the slope-intercept form:

- y = the value from the y axis

- x = the value from the x axis

m = the slope

b = the y-intercept )

2. Now, your equation should be y = -5x + 4. The first thing you're going to plot is the y-intercept.

To plot the y-intercept (also known as b or 4), just plot whichever number is "b" in the y-axis (the one that is vertical). In this case, your "b" is 4.

Now, the slope. The slope is rise/run. Meaning, you go up before you go down. This works really well with a fraction, but you might be confused as to what we do given a whole number like -5.

Simple! -5/1 . So, from 4 in the y-axis, you will go down 5 "cubes" in the graph, and 1 to the right.

Note: if this was 5/-1 , you'd go UP 5 cubes and 1 to the LEFT.

and you're done!
