Question

Find the x- and y-intercepts of the graph of
x + 2y = 28.

Answer 1

(0,14) This is the y intercept.

(28,0) This is the x intercept.

Explanation:

Let x = 0

x + 2y = 28

0 + 2y = 28

2y = 28 Divide both sides by 2

x = 14

(0,14) This is the y intercept.

Let y = 0

x + 2y = 28

x + 2(0) = 28

x + 28

(28,0) This is the x intercept.
