Question

Choose an equation in slope-intercept form for the line that passes through (0,7) and is parallel to the y=4x-19.


Select one:
a. y = 4x + 3
b. y = 4x + 7
c. y= (1/4)x - 7
d. y= (1/4)x + 9

Answer 1

Hint: any two parallel lines have the same slope, so your answer will be an equation with a slope of 4 (since y = 4x - 19 has a slope of 4)

Answer 2

you just need to make sure that the equation goes through (0,7)

Answer 3

thank you! i will try it now.

Answer 4

ok tell me what you get

Answer 5

i don't get how to set it up.

Answer 6

y = mx + b

y = 4x + b ... we know the slope is 4, so plug it in

Answer 7

we also know that it must go through (0,7), so plug in x = 0 and y = 7

y = 4x + b

7 = 4(0) + b

7 = 0 + b

7 = b

b =7

So because m = 4 and b = 7 we go from

y = mx+b

to

y = 4x + 7

Answer 8

i got it :) thank you!

Answer 9

now i know how to set them up

Answer 10

that's great, yw
