Question

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

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

Answer 1

The coefficient of x is the value for slope in y-intercept form, and the number that we add or subtract is our y-intercept. So in this case, we want to look for a "-2" in front of x and a +4 in the equation.
Answer choice A fulfills those conditions. (I am also assuming that answer choice A should have had an x in it, but you accidentally forgot to type it.)
