<em>The coefficient of x is 8</em>
Answer:
-1
Step-by-step explanation:
x y x2 y2
-3,5 and 5,-3
-3-5/5-(-3)
-8/8
the slope is -1/1
y2-y1 / x2-x1=slope of the two points
Answer:
Square (top right), rectangle (middle bottom), and trapezoid (bottom right)
Step-by-step explanation:
The only one I'm not to sure about is the trapezoid, but you can rule out all the others because there is no right angle. Hope this helps!
