Question

Which of the following shows the equation of a line with a slope of -3 and a y-intercept of -1?

A) y = -3x - 1
B) y = -x - 3
C) y = -3x + 1
D) y = -x + 3
I am confused and hope that someone maybe able to help me. Thanks

Answer 1

a y=-3x-1

Answer 2

y = m x + c
where m is slope and c is y intercept.

Answer 3

I am a little confused still but I am thinking answer is A

Answer 4

compare equation with y =mx+c which gives u m=-3 and c=-1 hence only option A is right.
