Question

Find the slope of the line that passes through the points (-2, 3 ) and (5, 7) .

a. 7

b. 4/7

c. 3

d. 1/2

Find the slope of the line that passes through the points ( 1,2) and (2,5).

a. 6

b. 8/3

c. 3

d. 1/2

Answer 1

1. b) 4/7

2. c) 3

Explanation:

(-2, 3 ) and (5, 7)

Slope: (7-3)/(5--2)

4/7

( 1,2) and (2,5)

Slope: (5-2)/(2-1)

3/1

3

Answer 2

1. b. 4/7

2. c. 3

Explanation:

To find the slope

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

m= (7-3)/(5 - -2)

= (7-3)/(5+2)

= 4/7

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

m= (5-2)/(2 - 1)

= 3/1
