Question

A line that includes the point (-5, 10) has a slope of 5. What is its equation in point-slope form?

Answer 1

y - 40 = 5(x +5)

Explanation:

give m = 5, y = 10, x = -5

y = mx + b

10 = 5(-5) + b

10 = -25 + b

b = 10 + 25 = 35

so y = 5x + 35

so point slope form: y – y1 = m(x - x1)

y - 40 = 5(x +5)
