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.
The absolute value - or distance from zero, is fairly simple to find. Make your final answer positive to find it.
We can get rid of the parentheses so it looks like this:
3x + 24x + 8.
Simplify:
27x + 8
Answer:
The slope of the line is -5
