Question

Solve m=
y - y1/x-x1 for y, where m= slope and (x, y) and (x1,y1,) are ordered pairs

Answer 1

y = m(x - x₁) + y₁

Explanation:

Given expression for the slope of a line is,

m =
`(y-y_1)/(x-x_1)`

Here (x, y) and (x₁,y₁) are the ordered pairs lying on the line.

We have to solve this expression for the value of y.

m(x - x₁) = (y - y₁)

m(x - x₁) + y₁ = y

Therefore, y = y₁ + m(x - x₁) will be the answer.
