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. -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

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
