Exercise 24 Page 142

The slope-intercept form is y=mx+b.

Error: Misinterpretation of the slope-intercept form
Correct Solution: The slope is 3, and the y-intercept is -6.

Practice makes perfect
Every linear equation can be written in slope-intercept form.

y= mx+ b In this form m is the slope and b is the y-intercept. Let's rewrite our equation so it matches this form. y=3x - 6 ⇔ y= 3x+( - 6) Now we can identify the y-intercept as -6 and the slope as 3. We can see that the error was a misinterpretation of the slope-intercept form.
