Question

Given a line passing through points (1, 0) and (4,9),
what is the slope of the line?

Answer 1

3

Explanation:

The slope (m) is the ratio of the difference in y-values to the corresponding difference in x-values:

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

m = (9 -0)/(4 -1) = 9/3

m = 3

The slope of the line is 3.
