Explanation for Question 10 From the Math (No Calc) Section on the 2019 May Sat
Question 10 says the graph in the X, 2 Y plane of the linear function app contains the 0.34 for every increase 3 of five units and acts after-effects increases by three units, 4 which of the following equations to find the function. 5 Now, if you notice all of the answer choices are in Y equals MX 6 plus B form, and not only are they all in that form, 7 but they all have different values for M which is the slope, 8 which means that all we need to do to find the answer to this 9 question is to figure out what the slope is. 10 And we're actually explicitly told in the problem. 11 We don't even have to calculate that for every five increases in X, 12 F of X increases by three. 13 Now, since F of X is equal to Y we know the rise is 14 three and the run is five, 15 which means that the slope is three over five. 16 And the only possible answer, the only equation that has a slope or an 17 M value of three over five is answer C. 18 So that must be the correct answer.
