Lesson 2: Zeroes of Linear Functions

What does the y-intercept represent in a real-world scenario?

How can you identify the zeroes of a linear function from its graph?

linear equation
y-intercept
zeroes
ordered pair
x-coordinate
y-coordinate

8.EE.B.5: Graph proportional relationships, interpreting the unit rate as the slope of the graph.

Students will transition from graphing points on a line to identifying key features of linear functions, specifically y-intercepts and zeroes, in both mathematical and real-world contexts. (DOK 2)

Confusing the x-intercept (zero) with the y-intercept.

Difficulty identifying zeroes from a table versus a graph.
