To determine the equation of the line that has slope m=1/3 and passes through the point (3,2) you have to use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

Where

m is the slope of the line

(x₁,y₁) are the coordinates of one point of the line

Replace the formula above with the known information about the line:

[tex]y-2=\frac{1}{3}(x-3)[/tex]

Next is to write the equation in slope-intercept form, which means that you have to leave the y term alone on the left side of the equation and all other terms have to be on the right side.

-First, distribute the multiplication on the parentheses term:

[tex]\begin{gathered} y-2=\frac{1}{3}\cdot3-\frac{1}{3}\cdot3 \\ y-2=\frac{1}{3}x-1 \end{gathered}[/tex]

-Second, pass "-2" to the right side of the equation by applying the opposite operation, "+2", to both sides of the equal sign:

[tex]\begin{gathered} y-2+2=\frac{1}{3}x-1+2 \\ y=\frac{1}{3}x+1 \end{gathered}[/tex]

So, the equation of the line with slope 1/3 that passes through the point (3,2), expressed in slope-intercept form is:

[tex]y=\frac{1}{3}x+1[/tex]
