Question

Write the slope-intercept form of the equation of the line through the given point with the

given slope.
through (1,5), slope = 3

Answer 1

y = 3x +2

Explanation:

we use the formula, slope= rise/run

we use the one known point and the slope and assume one point is (x,y)

G = ∆x/∆y

3 = y-5/x-1. we then cross multiply

3x - 3 = y - 5

we make y the subject of the equation

y = 3x +2
