Question

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

y = 2x + 4

y = 2x – 4

y = –2x – 4

y = –2x + 4

Answer 1

Answer:y=-2x+4

Step-by-step explanation:took the test and got it right

Answer 2

y=-2x+4 would be the correct answer because the slope-intercept form (y=mx+b) says that "m" is the slope (in which this case is -2) and that "b" is the y-intercept (In this case, it's 4).
