Question

If (k,6k) and (3k,10k) are two points on the graph of a line and K is not equal to 0, what is the slope of the line?

Answer 1

Explanation:

slope = y2-y1/x2-x1

Given the coordinates (k,6k) and (3k,10k)

x1 = k

y1 = 6k

x2 = 3k

y2 = 10k

Substitute

slope = 10k-6k/3k-k

slopw = 4k/2k

slope = 4/2

slope = 2

Hence the slope of the line is 2
