Question

What equation has an x-intercept of 12 and a y-intercept of 6.
A. 2x+3y=18
B. -2x+3y=18
C. x+2y=12
D. 2x+2y=4

Answer 1

if an equation has an x-intercept of 12, then the point (12,0) lies on the line

Answer 2

so check equation A

2x+3y=18

2(12)+3(0)=18 ... plug in x = 12, y = 0

24 + 0 = 18

24 = 18 ... which is false, so (12,0) does NOT lie on the line 2x+3y = 18

Answer 3

This shows us that 2x+3y = 18 does NOT have an x-intercept of (12,0)

Answer 4

x intercept is what you get when you plug in y = 0, and y intercept is what you get when you plug in x = 0

Answer 5

So plug those in until you find which equation has x = 12 and y = 6.

Answer 6

okay thanks :)
