Question

Which of the following has a slope of –2 and a y-intercept of 4?

A. y = 2x + 4
B. y = –2x – 4
C. y = –2x + 4
D. y = 2x – 4

Is it D?

Answer 1

Answer 2

y = mx +b

slope = m
y intercept = b

you got the positive signs mixed up, but good try!

Answer 3

So this would be B?

Answer 4

No, the y intercept is positive 4
you got the slope right this time though

Answer 5

Oh.. A?

Answer 6

No.
It is C.

y = -2x + 4
y = mx + b
m = -2
y = 4

Answer 7

Oh.. sorry :(

Answer 8

good try, though.
just remember you don't need to look at the answer choices
you are given m and b
just plug those into y = mx + b
y = (-2)x + (4)
y = -2x + 4

Answer 9

Oh, ok. Thanks!
