A) y=1/2x + 4/3
b) y=-2/5x + 6
Answer:
(B) The exponents should be subtracted by the quotient rule of exponents
Step-by-step explanation:
Let's examine how this was solved.

He first rose everything in the parentheses to the second power, which is just multiplying all the exponents by 2. This is correct.

He then combined the numerator exponents. Exponent rules say that
, so he should have ended up with
, which he did. This is correct.

Now, what he did in the final step is wrong. He added the exponents. However, exponent rules tell us that when we have
, it equals
.

So the final answer should have been

Answer:
y = -5(x-1)
Step-by-step explanation:
A y-intercept of 1 means that the point (0,1) falls on the line.
Slope-intercept form is
where m is the slope...
Therefore, the slope-intercept equation is y-1=-5(x-0) or y-1=-5x
