Let's first calculate the slope, which is taken by dividing the change in y by the change of x.

6-4=2

4-3=1

The slope is 2.

Now that we know the slope is 2, we can plug in two coordinates to solve for the y-intercept, represented as b.

Let's pick (3,4).

So, y=2x+b

4=6+b

-2=b

The equation is 2x-2

Check: 4=(2*3)-2
