Explanation for Question 19 From the Math (No Calc) Section on the Official Sat Practice Test 8
So number 19 tells us that there's a startup company that opened with eight 2 employees, that company's growth plan assumes two new employees every 3 quarter for the first five years. 4 Right? So they're growing by two employees every three months for five years, 5 if an equation is right. And then the form Y equals MX plus B, 6 then employed by X quarters after your company open, 7 what is the value of B? Right. And so we see that why is 8 the people employ the number of employees? 9 And when we think about a graph, right, or B is our Y intercept, 10 which we can also think of as our starting point. 11 So we want to think about how many employees did the company start with 12 at year zero when they first started and when the company opened, 13 they had eight employees. So we're starting with eight employees. 14 That means that our Y intercept B is going to be equal to eight.
