Question

Find the slope of the line that passes through the points (1, 4) and (3, –2).

1. -3
2. -1/3
3. 3
4. 1/3

Answer 1

Answer

1. -3

Explanation

The slope of a line is calculated as follows;

slope = (change in y-axis)/(change in x-axis)

= Δy/Δx

Δy = 4 - -2 =4+2 = 6

Δx = 1 - 3 = -2

∴ Slope = 6/-2

= -3

The answer is 1. -3
