Question

What is the equation of the line that passes through the point (2,-6) and has a slope of -3?

Answer 1

Answer is y = -3x

Step by step

We can use point slope form to solve

y - y1 = m (x - x1)
Substitute your x and y and slope

y - -6 = -3 (x - 2)
Distribute

y + 6 = -3x + 6
Subtract 6 from both sides


y +6 -6 = -3x + 6 - 6
Combine

y = -3x is your answer
