Answer:a is 5, b is 6, c is 8, d is 17 by comparison of the general equAtion. So plugging that into the formula that’s given we get (5-17)/(6+8)=-12/14=-6/7. By the way, I think there’s supposed to be “+d” instead of “d” and “+17” instead of 17.
Answer:
have one bar be red and the other be blue
y = 2/7 x - 51/7
Step-by-step explanation:
Equation of the line
(y-y1)/(y2-y1) = (x-x1)/(x2-x1)
(y-(-7)/(-9-(-7) = (x-1)/(-6-1)
(y+7)/-2 = (x-1)/-7
(-y-7)/2 = (-x+1)/7
-y-7 = -2/7 x + 2/7
-y = -2/7x +2/7 + 7
y = 2/7 x - 2/7 - 7
y = 2/7 x + (-2-49)/7
