Answer:

The point-slope equation of this line is y + 8 = 16(x - 8)

Explanation:

In order to find this, we first need to find the slope using the slope formula.

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

m = (8 - -8)/(9 - 8)

m = 16/1

m = 16

Now that we have the slope, we can use either point and the slope to plug into the point-slope base form.

y - y1 = m(x - x1)

y - -8 = 16(x - 8)

y + 8 = 16(x - 8)

If your equation start off as y-8 then this your Answer: y-8= 16(x-9)

Step-by-step explanation: Slope= 8-(-8)/9-8

=16/1

= 16

So we need to use the point (9,8)

Y-8=16(x-9)
