Question

What is the equation of a line the passes through the point (-1,3) and has a slope of -3?

Answer 1

Given points ( -1 ,3 ) and slope(m) = -3

Explanation:

The equation of a line is given by

y - y1 = m ( x - x1 )

y - 3 = -3 ( x +1 )

y - 3 = -3x - 3

3x + y -3 +3 =0

3x + y = 0

which is the required equation
