Which formula is equivalent to the slope formula

Question

Consider the formula for the slope between two coordinate points, m, shown below.

M=y2 minus y1 over x2 minus x1

Which of the following equations is equivalent to the slope formula?

A.) Y2=m(x2-x1)+y1

B.) X2=m(y2-y1)+x1

C.) Y1=m(x2-x1)+y2

D.) X1=m(y2-y1)+x2

Answer 1

m = (y₂ - y₁) / (x₂ - x₁)

y₂ - y₁ = m(x₂ - x₁)

y₂ = m(x₂ - x₁) + y₁

The answer is Choice C.
