Exercise 5 Page 347

Everything necessary to use the point-slope form has been given in the problem.

y-4=3/4(x-3)

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 ( 3, 4) and the slope 34, so we have everything we need to create a point-slope form equation. y- 4= 34(x- 3)
