Question

(40, 3,000) and (60, 4,000)
find the slope of the line that passes through

Answer 1

slope of the line is 50

Explanation:

The slope of a line (gradient) is determined by the rise/run so

(y2 - y1) / (x2 - x1)

We simply substitute in our coordinates and solve. So:

(4000 - 3000) / (60 - 40)

= 1000 / 20

= 100/2 = 50

Gradient is 50
