Answer:

Slope Intercept Form: y=3x+10

Slope: 3

y: 10

Step-by-step explanation:

y-3x=10    Add 3x to both sides. The y has to be isolated.

So it is y=10+3x     So we have to reorder it so y=3x+10

Question #2 What is the difference?​
e-lub [12.9K]

Answer:

B  \frac{b-10}{b-1}

Step-by-step explanation:

In order to get the same denominator, we need to multiply the second fraction by (b+2) in the numerator and denominator.

We will end up in something like this :\frac{b^{2} - 2b - 8 -6(b+2) }{(b-1)(b+2)}

I just timed the second fraction by b+ 2 and then i added them together.

Therefore, we will get \frac{b^{2} - 8b - 20}{(b-1)(b-2)}

now factoring the numerator we will end like this

\frac{(b-10)(b+2)}{(b-1)(b+2)}

we will then end up with the answer.

Hope this helps.
