# Chapter 3 - Introduction to Graphing - 3.3 Graphing and Intercepts - 3.3 Exercise Set - Page 178: 6

$\color{blue}{\text{y-intercept}}$

#### Work Step by Step

RECALL: (1) An x-intercept is a point were a graph touches or crosses the x-axis. Its coordinates are $(a, 0)$. (2) A y-intercept is a point were a graph touches or crosses the y-axis. Its coordinates are $(0, b)$. This means that the point $(0, 7)$ could be a y-intercept but not an x-intercept of a graph. Thus, the missing expression in the given statement is: $\color{blue}{\text{y-intercept}}$
