Someone please help I don’t understand

Answer:
D 2n+2
Step-by-step explanation:
We can check the slope of the function
m = (y2-y1)/(x2-x1)
= (10-8)/(4-3)
= 2/1
The slope is 2
We can use the point slope form of a line to calculate the equation for a line
y-y1 = m(x-x1)
y-2 = 2(x-2)
Distribute
y-6=2x-4
Add 6 to each side
y-6+6 = 2x-4+6
y = 2x+2
