Exercise 41 Page 313

Rewrite the equation in slope-intercept form.

Slope: 9
y-intercept: - 15

Practice makes perfect

Let's recall the slope-intercept form of a line. y= mx+ bHere, m represents the slope of the line and b is the y-intercept. Let's rewrite the given equation in slope-intercept form. To do so, we have to isolate y by using inverse operations and Properties of Equality.

- 2y=6(5-3x)
