Answer:

Step-by-step explanation:
We were given that:
and 
When x=5


When x=6


This implies that:

Answer:
y = -7x + 17
Step-by-step explanation:
you want to isolate the 'y' variable, start by distributing -7 on the right side
y + 4 = -7x + 21
now subtract 4 from each side
y = -7x + 17
4. -5
5. -3
7. 17
8. 5
9. -101
10. 0
11. 16
Everything else you did is correct
Hope this helps ya
Answer:
D
Step-by-step explanation:
A) Incorrect. x = 4 means that all points on the line must have x coordinate equal to 4. Neither points satisfy this.
B) Incorrect. We can rewrite the equation to be y=x/4. If we calculate the slope between the two points we get a slope of 0, not 1/4.
C) Incorrect. If y = 3, all points must have y coordinate equal to 3. Neither points satisfy this.
D) Correct. If y = 4, all points must have y coordinate equal to 4. Both points satisfy this.
