Question

What is the equation of the line passes through (2,3) and (-2,1)?

Answer 1

`y=1/2x+2`

Explanation:

First, I would want to find the slope of the line. For this, you would do the change in y over the change in x
`(Y_2-Y_1) / (X_2-X_1)=`

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

`2 / 4 = 1/2`
.5 this means that the slope is .5 or 1/2

Then, you need to find the y intercept, by using point-slope form
`y-y_1=m(x-x_1)`
`y-3=1/2(x-2)`
`y-3=1/2x-1`
`y=1/2x+2`
