Exercise 2 Page 203

Use the format for the point-slope form, y-y_1=m(x-x_1).

y-6=3/5(x-5)

Practice makes perfect

An equation in point-slope form follows a specific format.

y- y_1= m(x- x_1) In this format, m represents the slope and the point ( x_1, y_1) lies on the graph of the line. We are given the point ( 5, 6) and the slope 35, so we have everything we need to create a point-slope form equation. y-y_1=m(x-x_1) ⇕ y- 6= 3/5(x- 5)
