How did you get your first 3 answer just out of curiosity?
3. a. h(2)=1
b. h(-5)=57
c. h(-8)=111
4. a. g(9)=6
b. g(-1)=-14
c. g(-3)=-42
5. a. f(60)=140
b. f(0)=32
c.f(25)=77
Volume of the flour = 2 3/4
Volume of the sugar = 13/8
Volume of the butter = 1/2
Total volume
2 3/4 + 13/8 + 1/2
11/4 + 13/8 + 1/2
(22+13+4) / 8
39 / 8
4 7/8
(the number) - 2 = 25
(the number) = 25 + 2
(the number) = 27
The answer is 39/8

<span>The first choice is correct.
Explanation<span>:
The formula for slope is m=(y</span></span>₂<span><span>-y</span></span>₁<span><span>)/(x</span></span>₂<span><span>-x</span></span>₁<span><span>). Once we find the slope using that formula, it goes in place of m in y=mx+b.
We do not yet have the y-intercept, but we can use one of the points to find it. We substitute the x-coordinate of one point in for x and the y-coordinate of the same point in for y; then we solve for b. This gives us the y-intercept.</span></span>
