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:
-1
Step-by-step explanation:
The slope of a line between two points is given by the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (7 -(-3))/(-2 -8) = 10/-10
m = -1
The slope of the line is -1.

Answer:
Step-by-step explanation:A triangle is aptly named: it is composed of three (tri) angles formed by three non-coincident, non-parallel lines. That the lines are non-coincident means they do not overlap, and that they are non-parallel means that each line intersects with every other line. Correspondingly, a triangle also has three sides.
