Question

Find the slop of the line passing through the point (-9,-3) and (7, -7)

Answer 1

`slope=-(1)/(4)`

Explanation:

To find the slope of the two points (-9,-3) and (7, -7) w have to use the slope formula

`slope=(y_(2)- y_(1) )/(x_(2) -x_(1) )`
`slope=((-7)- (-3))/(7 -(-9) )`

`slope=(-4 )/(16)=-(1)/(4)` can also be written as a decimal
`slope=-0.25`

we get - 1/4 because -4 divided by -4 is 1 and -4 divided by 16 is -4
