Question

Which of the following is the equation of the line that has x-intercept -2 and y-intercept -6?

А. y=-3x - 6
B. y=-2x - 6
C. y=-6x-2
D. y = 3x - 2

Answer 1

a

Explanation:

0 = m(-2)-6

M = -3

Y = -3x-6

Answer 2

a

Explanation:

y=mx+c, where c is the y-intercept. hence,

y=mx-6

at the x-intercept, y=0 and x = -2

0 = m(-2)-6

2m = -6

m = -3

y = -3x-6
