Question

Explain how to graph x + 3y = 9 using the x- and y-intercepts method. Be sure to use complete sentences and use the x- and y-intercepts method only.

Answer 1

if you write your equation in the form y=mx+c
you would have a - slope.
to find x-intercept, y=0
x+3(0)=9
x=9
to find y-intercept, x=0
0+3y=9
y=3
