Convert y-3=(1/3)(x+1) to slope intercept form

Mekhanik [1.2K]

Slope-intercept form is $y=mx+b$ , where m is the slope and b is the y-intercept.

Here, we first need to distribute the 1/3.

$y-3= \frac{1}{3} x+\frac{1}{3}$

Next, we add 3 to both sides of the equation.

$y= \frac{1}{3} x+\frac{10}{3}$

To find the slope of a line from two points we use

m = (y2-y1)/(x2-x1)

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

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