Question

What is an equation of the line that passes through the points (0,−3) and (-5, 3)?

Answer 1

y = -6/5x - 3

Explanation:

Slope m = (y2-y1)/(x2-x1)

using (0,-3) and (-5,3)

m = (3 - -3)/(-5 - 0)

m = (6)/(-5) = -6/5

Slope-intercept: y = mx + b

using (-5,3)

3 = -6/5(-5) + b

3 = 6 + b

b = -3

y = -6/5x - 3
