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: -2=3(5)+b
Step 2: -2=15+b
Step 3: -2+15=15+15+b
Step 4: -13=b
Step 5: y=3x - 13
Analyze the steps. In which step did the Jolon make an error?
A. He switched the x- and y- values in step 1.
B. He multiplied incorrectly in step 2.
C. He added 15 to both sides in step 3.
D. He forgot to add the b-value in step 5.

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!! 30 POINTS!!!!!!!!!!!!!!!!!!!!!!!

Respuesta :

He made a mistake at step 3. He should subtract 15 from both side instead of adding 15 to both side.

Answer: C

Answer:

C. He added 15 to both sides in step 3.

Step-by-step explanation:

In order to isolate the b term, Jolon should subtract 15 to both sides in step 3, as follows:

Step 1: -2=3(5)+b

Step 2: -2=15+b

Step 3: -2-15=15-15+b

Step 4: -17=b

Step 5: y=3x - 17
