Question

What is the equation in point-slope form and slope intercept form of the line given slope -2, (3, 1)?

Answer 1

`(y-1) = -2(x-3)`

`y = -2x+7`

Explanation:

Point slope form is:

`(y-y_1) = m(x-x_1)`

`(y-1) = -2(x-3)`

Now convert it to slope intercept form:

`y-1 = -2x+6`

`y = -2x+7`

graph{y = -2x+7 [-7.38, 12.62, -0.96, 9.04]}
