Answer:

2y-x=6

Step-by-step explanation:

Standard form is ax+by=c.

Slope form : y=mx+n where m is slope n-y intercept.

First we write in slope form

$y=\frac{1}{2}x+3$

Now we can multiply both sides by 2.

2y=x+6

Subtract for each side x

2y-x=6

Yakvenalex [24]

Answer:

Hence final answer is B: Step 2.

Step-by-step explanation:

Step 1: Find the total points needed to score in six games: 96x6=576

Justification:

Product of 96 and 6 is 576 which is same number found by Brenda. So step 1 is correct.

Step 2: Find the total points scored: 92+110+85+78=365

Justification:

Sum of total points scored by Brenda is 92+110+85+78= 461.

But she got different value 365.

Hence step 2 is wrong.

Hence final answer is B: Step 2.
