Question

Graph the equation by plotting points:y=-2x+4

Answer 1

Here are a few points to graph:

To find the coordinates of a point you will have to substitute the x for y value then find the y. For example:

if we substitute x for-2 the equation will become: y=(-2*-2)+4=4+4=8. and so on so here are a few x points:

X=-2: Y=4+4=8

X=-1: Y=2+4=6

X=0: Y=0+4=4 (X-INTERCEPT)

X=1: Y=-2+4=2

X=2: Y=-4+4=0 (Y-INTERCEPT)

X=3: Y=-6+4=-2

X=4: Y=-8+4=-4

X=5: Y=-10+4=-6

I hope this helps :)
