Question

Jolon used the slope-intercept form to write the equation of a line with slope 3 that passes through the point (5, –2). His work is shown below.

Step 1: Negative 2 = 3 (5) + b
Step 2: negative 2 = 15 + b
Step 3: Negative 2 + 15 = 15 + 15 + b
Step 4: Negative 13 = b
Step 5: y = 3x – 13

Analyze the steps. In which step did the Jolon make an error?

Answer 1

Answer 2

step 3

Explanation:

He should have subtracted 15 instead off adding 15. this would have gotten rid of the fifteen on the right side and left him with -17=b. Instead, he would have added 15 and gotten 13=30+b. That threw off the rest of the equation. The rest of the equation is wrong. b should equal -17

the slope-intercept equations should be y=3x-17
