Question

Find the slope of the line that passes through each pair of points.

1. A(0,1), B(2,7)
2. C(2,5), D(3,1)
3. E(1,2), F(4,7)

THANK YOU IN ADVANCE 

Answer 1

1) 
$\sf Slope = \frac{y_2-y_1}{x_2-x_1} = \frac{7-1}{2-0} = \frac{6}{2} =\boxed{3}$

The slope of the line that passes through points (0,1) and (2,7) is 3

2)
$\sf Slope = \frac{y_2-y_1}{x_2-x_1} = \frac{5-1}{2-3} = \frac{4}{-1} =\boxed{-4}$

The slope of the line that passes through points (2,5) and (3,1) is -4

3)
$\sf Slope = \frac{y_2-y_1}{x_2-x_1} = \frac{7-2}{4-1} = \frac{5}{3} =\boxed{1\frac{2}{3}}$

The slope of the line that passes through points (1,2) and (4,7) is 5/3 or 1 2/3
