Answer:
a. y = -2x + 7
Step-by-step explanation:
First, find the slope by plugging the points into the slope formula, 
, which equals -2. Then use the slope and the point (7,-7) to make an equation in slope-point form. y+7=-2(x-7), finally solve for y to get y=-2x+7.
Answer:
This is one of many possible answers.
(x -1)(x-2)(x-3)
Explanation:
The zeros are x = 1, x = 2, x = 3. This polynomial has a degree of 3.
Cross multiply to get 8k+24=56 then solve for k so subtract 24 from each side to get 8k=32 so k=4
