Question

Write the equation of the line in slope intercept form slope =-9 through (-5,5)

Answer 1

y = 9x - 40

Explanation:

Using the point-slope equation of a straight line is the fastest approach here, since we already have the slope and a point:

y - k = m(x - h) becomes y - 5 = -9(x + 5)

Solving for y, this becomes y = 9x + 5 - 45, or y = 9x - 40
