Exercise 40 Page 143

Rewrite the equation in a slope-intercept form.

Error: Slope not identified correctly.
Correct graph:

Practice makes perfect
Let's rewrite the given equation in slope-intercept form first. y+1=3x ⇔ y=3x-1

Now we can identify the y-intercept as -1, which has been graphed correctly. Additionally, the slope is 3. This means that for every step we take to the right, the function increases by 3 steps up.

Graphing the Function

Let's graph the function and see if it overlaps with the given graph.

The graphs do not overlap. The error committed was not graphing the slope properly.
