(2,60)(4,240)......t = x and d(t) = y
average rate of change (slope) is (y2 - y1) / (x2 - x1)
slope = (240 - 60) / (4 - 2) = 180/2 = 90 m/s
It represents the average distance traveled by the object between 2 seconds and 4 seconds
The x intercept is the amount of money she has and I don't know what it is.... sorry. I knew what it stood for though.
The y- intercept has to be a point in the line where x is 0. Which means that in this case it would be -4.
To find the slope, use the formula: rise over run —> y2 - y1/x2 - x1
Choose any two coordinates and plug them in. Then simplify. Let me know if you have any questions by commenting:)
Hope I helped:)

If the 3 is an exponent, then the person above me is right.
Use Pythagoras 6 squared =36-(4x4) =20 square root of 20 then times that by two
