Question

Choose the equation of the line passing through the point (1, -5) and parallel to y = 2x + 4.

Answer 1

Ok, so first you need to find the slope

Answer 2

Which is 2, then multiply by the x coordinate of the point you want it to go through, which is 1, so it becomes 2. To get -5 from 2, you must subtract 7. The equation becomes y=2x-7

Answer 3

is the answer y = 2x - 3 ?

Answer 4

No, 2x-7

Answer 5

Because the slope times the x coordinate of the point you want it to go to is 2. You need y=(-5). So you need to subtract 7 from your answer, therefore it becomes 2x-7=y

Answer 6

Do you understand now?

Answer 7

ohhh ok i get it now
