Question

Does the line y = 3x – 7 pass through the point (6, 11)? Explain your answer.

Does the line y = 18 – 5x pass through the point (4, -4)? Explain your answer.

Answer 1

1. Yep

2. Nope

Explanation:

1. All you do is substitute x (6) and y (11) into y = 3x-7

11 = 18 - 7

This is true since 18 - 7 equals 11. so the line pass through the point (6,11)

2. Substitute x (4) and y (-4) into y= 18-5x

-4 = 18 -5(4)

-4 = 18 - 20

18-20 equals to -2, not -4

So, the line does not pass through the point (4,-4)
