Answer:

The point slope form of this equation would be y - 8 = 2(x - 1)

Step-by-step explanation:

In order to find the equation, we first must find the slope. For this we can use the slope formula.

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

m = (10 - 8)/(2 - 1)

m = 2/1

m = 2

Now that we have this, we can put it in the equation along with either point.

y - y1 = m(x - x1)

y - 8 = 2(x - 1)
