<em>About how</em>
As with any graphing problem, when doing it by hand, one chooses enough points to give the general shape of the curve. In some cases, quite a few points may be required. It is often helpful to use a spreadsheet for calculating the point values. Here, we've graphed the equations using "technology"--a graphing calculator.
The answer is C.

Next we multiply 1 by 8 and add it to the 7,
1 x 8 +7 = 15, so therefore it’s 15/8, please give me a thanks and 5 stars along with brainliest!
Answer:
D. y=-2x
Step-by-step explanation:
A linear equation is y=mx+b. M is given as -2. Because the line passes through (0,0), it crosses the y axis at 0.
