Question

. Which of the following has a slope of 2 and a y-intercept of –4? (Points : 4)
A) y = –2x + 4
B) y = 2x + 4
C) y = 2x – 4
D) y = –2x – 4

Answer 1

general form is
y=mx+b
where m is slope
b is y-intercept

Answer 2

so the answer is C

Answer 3

In slope-intercept form, the slope is presented as a product of x while the y-intercept is a constant: y = mx + c. Can you work it out from there?
