Write the equation given the point 4,2 and slope 1/2
raketka [301]

Hello.

We have a point that the line passes through and its slope.

Let's write the equation in Point-Slope Form:

y-y₁=m(x-x₁)

In this case,

y₁=2

m=\displaystyle\frac{1}{2}

x₁=4

Plug in the values:

\mathrm{y-2=\displaystyle\frac{1}{2} (x-4)}

This is point-slope form. Now, what about Slope-Intercept?

First, we should distribute \displaystyle\frac{1}{2}:

\mathrm{y-2=\displaystyle\frac{1}{2} x-2}

Add 2 to both sides:

\mathrm{y=\displaystyle\frac{1}{2} x-2+2}

Simplify:

\mathrm{y=\displaystyle\frac{1}{2} x}

I hope it helps.

Have a nice day.
