Question

Choose the equation that represents the line that passes through the point (−1, 6) and has a slope of −3.

A.y = −3x + 3 

B.y = −3x − 6 

C.y = 3x − 3

D.y = 3x − 1

Answer 1

Use the equation y=mx + b where m is the slope and in this problem m=-3 so y= -3x + b for the point (-1,6) substitute this into the equation to get 6=-3•(-1) +b or 6=3 +b and b=3. So the equation of the line is y=-3x +3 which is answer A.
