Given points are

Next, find the slope.

Substitute 5 for y₂,  7 for y₁, 3 for x₂, and  0 for x₁  in slope formula.

                       (Subtract: )

                          (Subtract: )

You know the slope and a point on the line, so use point - slope form

with either given point to write an equation of line.

Choose

            (Substitute 0 for y₁, 10 for x₁ and )

                  (Apply additive identity property: )        \ \

                      (Multiply: )

         (Add 7 to each side)

               (Apply additive inverse property: )

                      (Apply additive identity property: )

The equation of line is .
