The unit rate would be the slope, which is given in the equation as 18.25
To find if the given point would be on the graph, replace x with the x value of the point, solve the equation and see if it equals the Y value of the point:
Equation: y = 18.25x
Point: (8,146)
Solve: y = 18.25(8) = 146
This equals the y value of the given point, so this would be on the graph.
