Exercise 8 Page 318

You are given everything you need to use point-slope form.

y+4=6(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 6, so we have everything we need to create a point-slope form equation.

y-y_1=m(x-x_1)

Substitute x_1= 3,y_1= -4,m= 6

y-( -4)= 6(x- 3)

a-(- b)=a+b

y+4=6(x-3)
