Question

How do you determine the slope of the line passing through (-2, 3) and ( 4, 9 ) ?

Answer 1

See Explanation

Explanation:

The formula for slope is as follows:

`(y_2-y_1)/(x_2-x_1)`

So using your two points, (-2, 3) and (4, 9) we have
`x_1= -2`
`x_2= 4`
`y_1= 3`
`y_2= 9`

Plug into the formula: `(9-3)/(4-(-2))`

We get the slope as: `6/6`, which equals `1`

Slope = 1
