Question

Y=-5x i ned help i forgot how to do this i really forgot and im in clas with my laptop

Answer 1

When you're graphing a line in slope-intercept form (y = mx + b), your first step is to look at b, which is your y-intercept. The y-intercept is where your line touches the y-axis.

Slope-intercept form is y = mx + b, but for y = -5x doesn't have a b, so you have to add one. You can do this by adding + 0 to the end, since it won't change your equation.

y = -5x + 0

b = y-intercept = 0

m = slope = -5

So, your line will start at 0 on the y-intercept, which will be at the origin point (0,0).

Your slope is -5, or $\frac{-5}{1}$, so you'll go down 5 and then to the right 1.

A few points on your line should be (0,0), (1,-5), and (-1,5).
