Question

Find the slope of the line passing through the points (a,−a−8) and (a+h,−(a+7h)−8).

Answer 1

The slope of the line through points (x1,y1) and (x2,y2) is given by :
\(\huge m=\frac{y_1-y_2}{x_1-x_2}\)
now,just put the values and find m.

Answer 2

here x1=a, y1=-a-8
x2=a+h, y2=-(a+7h)-8

Answer 3

I did that but still having trouble getting the correct answer, thanks though

Answer 4

y1-y2 = 7h
x1-x2=-h
slope = -7
what was the given correct answer?

Answer 5

I wasn't making the h in the denominator negative. Thanks for your help!

Answer 6
