Explanation for Question 4 From the Math (No Calc) Section on the 2019 April Sat
So for number four, we want to know which of the following is an 2 equation of the line and the X, Y plane that has slipped too and 3 passes through the 0.03. So here we are given a point and a slope, 4 and we're looking for the equation of the line. 5 So the equation of this line, it can be found using point-slope form, 6 which is Y minus Y one equals M times 7 X minus X one. 8 So now we can plug in all our information. 9 Y minus Y one is three equals M is 10 two times X minus X one, 11 which is zero. So now we need to rearrange and distribute a little bit 12 to get it, to look like our answer choices. 13 So if we distribute the two, we get Y minus three equals two X, 14 because two times zero is just zero. 15 And then you can add over the three, which gives you Y equals 16 two X plus three, which is a.
