Question

A line has a slope of 3 and contains the point (−1, −8). Which equations represent the line? Choose all answers that are correct. A. −3x + y = −5 B. 3x + y = −5 C. (y – 8) = 3(x − 1) D. (y + 8) = 3(x + 1)

Answer 1

equation of line is y=mx+b
slope m=3
line passes through point (-1;-8) so x=-1 y=-8
put all value in equation
-8=3*(-1)+b
-8=-3+b
b=-5
si equation of line is y=3x-5
Answer: A. −3x + y = −5
