Question

2. Find the slope of the line graphed below.10764 32.1123 64 5 6 7 8 9 10

Answer 1

First, locate two points and locate the coordinates of the two points

Let choose (0, 9)

and (6,7)

Using the slope formula:

`\text{slope}=\frac{y_{2\text{ - }}y_1}{x_2-x_1}`

x₁= 0 y₁ = 9

x₂= 6 y₂=7

Substitute the values into tha formula;

`\text{slope =}(7-9)/(6-0)`

`=(-2)/(6)`
`=-(1)/(3)`

`\text{slope}=-(1)/(3)`
