Question 1.
First solve for slope:

Point-slope formula is:

where m = slope.
Plug in values for PS form:

So the answer is Choice 2.
Question 2.
Choice D.
Points given: (-10, -7) and (3, -7)
Both y -intercepts are equivalent to -7
Question 3.
Choice A.
Points given: (2, 4) and (2, -7)
Both x - intercepts are equivalent to 2
R is 4 if I'm wrong sorry
X-intercept : -9 (-9,0)
y-intercept: 3 (0,3)
<h2>Question: Factor: 4x2 + 4x</h2>
Find the GCF.

Factor out the GCF.

Simplify each term in parentheses.

Hence, the answer is 4x(x + 1).
<h2 /><h2>Question: Expand: -(x - 3) </h2>
Remove parentheses.

Regroup terms.

Therefor, the answer is 3 - x.
