Question

A line has a slope 7 and includes the points (-5,9) and (-6,k). what is the value of k?

Answer 1

k=2

Explanation:

m=(y2-y1)/(x2-x1)

(k-9)/(-6-(-5))=7

(k-9)/(-6+5)=7

(k-9)/-1=7

k-9=7*-1

k-9=-7

k=-7+9

k=2

Answer 2

2

Explanation:

k-9/-6+5

So -6--5 =-1 therefore k-9 must equal -7 so therefore it should be 2
