Chapter 3 - Introduction to Graphing - 3.5 Slope - 3.5 Exercise Set: 4

Answer

$y_2-y_1$; $x_2-x_1$

Work Step by Step

RECALL: The formula for the slope of a line is given by $\dfrac{y_2-y_1}{x_2-x_1}$ where $(x_1, y_1)$ and $(x_2, y_2)$ are two points on the line. Thus, the missing expressions in the given statement (in order) are: $y_2-y_1$; $x_2-x_1$
