An easy this to do is use desmos... an online graphing site that will allow you to graph the curves and points...
https://www.desmos.com/calculator
The alternate method is to subsitute each point into each equations...
I just did (-2, 2) into A... that point is not on the curve.. that would be the hard way. Subsituting x = -2 y = 18 so (-2, 2) isn't on the curve.
so eliminate A
repeat the process with B etc is (-2, 2) in on the curve, then select the next point and check.
That's why graphing is easier
Answer:
39 cm
Step-by-step explanation:
using the x component go find 12 cm width and follow the line up until it intersects the graph. then follow that point left to estimate the height at that point to estimate 37.5 but more accurately you can use the given equation y=3.25x and plug in your x of 12 to get y=39
