Answer:

y = 7/2x - 20.

Step-by-step explanation:

The slope of the given line is -2/7, therefore the slope of the line perpendicular to it is - 1/ -2/7 = 7/2.

When x = -4, y = -6 so we substitute x1 = 4, y1 = -6 and m ( the slope) = 7/2 in the point slope form of a line:

y - y1 = m(x - x1)

y - (-6) = 7/2(x - 4)

y + 6 = 7/2x - 14

y = 7/2x - 20.

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

Based on the situation above the inequality will he use to contradict the assumption is 
4:10 ≠ 6:14
if DE is parallel to BC
then
4: (4+5) = 6 : (6 + 8)
