Question

Use intercepts to graph the linear equation 3x - y = -5.

x intercept
y intercept
step by step

Answer 1

x intercept =(-5/3,0)

y intercept = (0,5)

Explanation:

FOR THE X INTERCEPT:

-plug 0 in for the y value because the y value is 0 at the x intercept.

* 3x-0=-5 ---> 3x=-5 -----> x=-5/3 while y = 0

FOR THE Y INTERCEPT

-do the same thing as the x intercept, but instead of making y 0, make x 0.

* 3(0) -y=-5 ----> 0-y=-5 -----> -y=-5 ------->y=5 while x=0
