Question

A line contains the points P(1, 1) and Q(7, 10). What is the slope of the line?

Answer 1

`(3)/(2)`

Explanation:

to find the slope (gradient) use the formula

`slope = (change \: in \: y)/(change \: in \: x)`

`slope = (10 - 1)/(7 - 1)`

`slope = (9)/(6)`

9/6 can be simplified to 3/2 (as you do 9 ÷ 3 = 3 and 6 ÷ 3 = 2)

the slope is 3/2
