Question

A line has slope -4 and y-intercept (0, -2). What is the slope-intercept form of the equation of this line?

A. y = -2x + 4
B. y = -2x - 4
C. y = -4x - 2
D. y = -4x + 2
Someone please help!

Answer 1

y=mx+b
m=slope
b=yint

Answer 2

there is only one answer that has the correct y-intercept do you know which one is it now?

Answer 3

Well you can eliminate A and B

Answer 4

Is it D???

Answer 5

close but no because the y intercept is -2 not +2

Answer 6

But if its a negative isn't it suppose to become a positive?

Answer 7

even if its the y intercept.

Answer 8

oh i see where you get confused
because the formula says y=mx+b
no the +b can be -b as well it depends on where the intercept is and is this case is negative

Answer 9

So then it would be C..?

Answer 10

yup

Answer 11

It's C cuz the slope (m) =-4 and the y-intercept (b)=-2 the slope intercept form is y=mx+b apply the givens y=-4x-2

Answer 12

Thanks for the help!

Answer 13

no problem :)
