This post explains and give practice opportunities related to TEKS A.3C:

graph linear functions on the coordinate plane and identify key features, including x- intercept, y- intercept, zeros, and slope, in mathematical and real-world problems

## Instruction

Students continue to apply their skill of graphing functions given a variety of information, including equations, the slope, and points on the graph.

Students also learn to identify key features of a linear function, such as the x-intercept, y-intercept, the zero (the x value that makes y = 0), and the slope.

Finally, students practice interpreting the meaning of both the x- and y-intercept in real-world situations.

## STAAR Practice

Between 2016 and 2023 (including redesign practice), this readiness standard has been tested 21 times on the STAAR test. Videos explaining the problems can be found below.
