Question

Anya graphed the line (y – 2) = 3(x – 1) on the coordinate grid. What is the slope of the line

Answer 1

Given a point-slope form equation, we can easily locate of the slope of the linear equation. As a review, the point-slope form can be expressed as 
$(y-y_{1}) = m(x-x_{1})$

where y₁ and x₁ are the x and y-coordinates of the equation and m is the slope. Seeing that (y-2) = 3(x-1) is already in this form, we can clearly see that the slope of the equation is equal to 3.

Answer: 3
