Answer:

D. y+15 = 4/5(x+5)

Step-by-step explanation:

A line contains the points (8,9) and (-12, -7).

(y2 - y1) = m(x2 - x1)

(9 - (-7))= m (8 -(-12))

16 = m*20

m = 16/20 = 4/5

Given line has slope m= 4/5.

Parallel line has the same slope m = 4/5.

Point-slope equation is (y - y1) = m(x - x1).

We have slope m = 4/5, and point (-5, -15).

So,

(y - (-15)) = 4/5(x - (-5))

y+15 = 4/5(x+5)

What are the domain and range of the function on the graph
Alex Ar [27]
<span>To find the domain, solve the inequality 4 - x > 0. x < 4. Thus, all numbers less than or equal to 4 represent thedomain for this function. When trying to find the domain and range from a graph, the domain is found by looking at the graph from left to right.</span>
