Question

A line has a slope of 2/5 and passes through the point(-3,1). if the line also passes through the point (7,k) what is the value of k?

Answer 1

the underlying slope formula here is

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

for this scenario that means taking

2/5 = (k - 1) / (7 - -3)

2/5 = (k - 1) / 10

4 = k - 1

k = 5
