Question

How do you write the equation in slope intercept form given (-10,2),(4,-7)?

Answer 1

`y=-9/14x-4 3/7`

Explanation:

Given -

`x_1=-10`
`y_1=2`
`x_2=4`
`y_2=-7`

`(y-y_1)=(y_2-y1)/(x_2-x_1)(x-x_1)`
`(y-2)=(-7-2)/(4-(-10))(x-(-10))`
`(y-2)=(-9)/(4+10)(x+10)`
`y-2=(-9)/14(x+10)`
`y-2=-9/14x-90/14`
`y=-9/14x-90/14+2`
`y=-9/14x-4 3/7`
