Question

5. Write the equation of a line that has a slope of -2 and cuts the y-axis at y=−3?


A. y = 2x +3
B. y = - 2x + 3
C. y = - 2x - 3
D. y = - 3

Answer 1

c

Answer 2

how ? i tho it be a

Answer 3

it would be a if the slope and y intercept were positive. Since they are negative it has to be a negative sign in front of each. y=mx+b
m=slope so, y=-2x+b
b= y intercept so, y=-2x+(-3)
and adding a negative is the same as subtracting so, y=-2x-3
