Question

Write the equation of the line that is parallel to the line y = -3x + 12 and passes through the point (-1, 6).

y = one thirdx + 7

y = -3x + 3

y = one thirdx + 3

y = -3x + 7

Answer 1

Could you please help me @iGreen

Answer 2

Parallel lines have the same slope..so we can eliminate two options already..which options are those?

Answer 3

Do you know what the slope of y = -3x + 12 is?

It's in the form of y = mx + b, where m = slope..so you can tell what the slope is just by looking at it.

Answer 4

@yoyogators

Answer 5

So the slope is -3?

Answer 6

Yep. So parallel lines have the same slope, so you can get rid of two options..the one's that don't have a slope of -3.

Answer 7

We can eliminate Options A and C because they have a slope of 1/3.

Answer 8

That leaves us with B and D.

y = -3x + 3

and

y = -3x + 7

We can plug in (-1, 6) into each of these and solve and see which one makes it true.

y = -3x + 3
6 = -3(-1) + 3

Multiply:

6 = 3 + 3

Can you add 3 + 3? @yoyogators

Answer 9

So it would be B?

Answer 10

Yep, because the equation matches the point, and it has the same slope.

Answer 11

Okay i see Thanks so much! :)
