Given points are

Next, find the slope.

Substitute 2.6 for y₂,  0.9 for y₁, 3.4 for x₂, and 0.6 for x₁  in slope formula.

                          (Subtract: )

                                   (Subtract: ) \ \

                                               (Divide: )

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 0.9 for y₁, 0.6 for x₁ and )

    (Apply distributive property: )

                  (Multiply: )

(Add 0.9 to each side)

              (Apply additive inverse property: )

                   (Apply additive identity property: )

                                       (Add: )

The equation of line is .
