Question

What is an equation of the line that passes through the point (4,-6) and has a slope of -3 solve problem

Answer 1

y = -3x + 6

Explanation:

1. the equation has a slope of -3 => y = -3x + b (b is the number we'll find now)

2. From the point (4,-6) => x = 4, y = -6

=> -6 = (-3)(4) +b

=> b = 6
