Make a scatter plot of the data below. x y 25 150 50 178 75 216 100 265 125 323 150 392 175 470.4 using the quadratic regression equation predict what the y-value will be if the x-value is 200.
a. y = 83.5
b. y = 346.9
c. y = 238.1
d. y = 555.5

By looking at the scatter plot we can predict that the answer will be higher than previous answers since there is a positive relationship between x and y. With this idea, we can determine that a. is not the answer. Since it is too small of a y value. It also can't be b or c since these values are also small. Therefore the answer is d, for an x value of 200 the y value should be 555.5 from the choices given.
