Felipe SAT tutor at Prepped and Polished tutoring and test prep goes over the point slope formula and shows you how you can apply it to SAT math problems on the SAT math no calculator section.
Today’s video is about important formulas in the math no calculator section of the SAT, specifically the slope-intercept form. Before we jump into a specific problem, let’s first review what the slope-intercept form of a line is and what equation we use to represent it.
The equation y= mx +B represents he slope-intercept form with two important variables here: m being our slope, which is a constant, it does not change, and b being our y-intercept, also not changing.
The problem that we just did kind of illustrates how the slope-intercept form of a line is used in problems on the SAT even though it won’t directly produce the answer that you’re looking for. In other words it won’t directly answer the question that the problem is asking. You need to know in order to be able to take those next two or three steps to produce the answer that they want so you must know it for the test.
