#see solution for details.
Step-by-step explanation:
-Draw a horizontal line across the subject line.
-If the drawn horizontal line intersects our subject line more than once, then the line is not function but a relation.

because 3×10 is 30 and so 3 out of 10 is 30
567 mph
The speed will actually just be the slope of the line. Slope is change in y-coordinates over change in x-coordinates. We can pick any two points for this; let's just do (1, 567) and (2, 1134).
Slope = (1134 - 567) / (2 - 1) = 567 / 1 = 567
The speed is thus 567 miles/hour.
