PLEASE HELP I AM SO CONFUSED

Answer:

Option D, 1

Step-by-step explanation:

Step 1: Determine what x1, x2, y1, y2 are

Slope = $\frac{y2 - y1}{x2-x1}$

(x1, y1) is (2, 8)

(x2, y2) is (6, 12)

Step 2: Plug into the formula to get the slope

Slope = $\frac{y2 - y1}{x2-x1}$

Slope = $\frac{12 - 8}{6 - 2}$

Slope = $\frac{4}{4}$

Slope = 1

5. h(x)=0.5x - 1 with domain (-♾, 4) what is the range

Rudiy27

We have a domain of a function, that is, which x-es can we throw in. But we are asking which y-s will we get given that we can only throw x-es in $(-\infty,4)$ .

Let's try $x=4$ even though we are forbidden to put 4 inside $h$ we are still able to do so.

So $h(4)=0.5\cdot4-1=2-1=1$ what we just got is the upper limit of the range. The lower limit is $h(-\infty)=-\infty$ .

So the range is just $(-\infty, 1)$ .

Hope this helps :)
