Answer:
$2
Step-by-step explanation:
You need 2 points to find the slope
2 points from the graph are (3, 6) and (4, 8)
The expression to find slope is:
(y2 - y1) / (x2 - x1)
You can use any point for 2 or 1, but their x and y values must match
(8 - 6) / (4 - 3)
2/1
Slope is 2
Since slope is the same as unit rate, the unit rate is also 2
