Question

What is the slope of the line that passes through the points (1, -9)(1,−9) and (4, -7)(4,−7)?

Answer 1

2/3

Explanation:

the slope is the difference between ys, divided by the difference between xs. In formula:

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

Substituting the values, we obtain:

[-7 - (-9)] / (4 - 1) =

= [-7 + 9] / 3 = 2/3
