Answer: y = -3x + 10

Explanation:

Using the formula for finding the equation of line ;

y -
y_(1) = m ( x -
x_(1) )


x_(1) = 4


y_(1) = -2

m = -3

Substituting into the formula , we have

y - (-2) = - 3 ( x - 4 )

y + 2 = -3x + 12

writing the equation of the line in slope - intercept form , this means that we must make y the subject of the formula , that is

y = -3x + 12 - 2

y = -3x + 10
