Question

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

y = -2x + 7

y = 2x - 3

y = 2x - 7

y = -2x + 3

Answer 1

to be parallel it needs to have the same slope, so slope = 2, you can cancel 1 and 4 choices

Answer 2

Parallel means same slope, so use 2. Now plug this and the points given into the point-slope formula

Answer 3

now use formula y = mx + b, find value of b, by plugging m = 2 x=1 and y = -5

Answer 4

@ivettef365 easier to use point-slope

Answer 5

wouldnt it be y = 2x - 3

Answer 6

how did you get to that answer ??

Answer 7

-5 = 2(1) + b solve for b

Answer 8

so its y = 2x - 7 ?

Answer 9

correct

Answer 10

There you go.
@ivettef365 how did you come up with that method?

Answer 11

thank you ;)
