Introduction to Graphing Linear Functions WORKSHEET

Suitable for Grades: 8th Grade, Algebra I

CCSS: 8.F.A.3

CCSS Description: Interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear. For example, the function A = s2 giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1), (2,4) and (3,9), which are not on a straight line.

Introduction to Graphing Linear Functions WORKSHEET DESCRIPTION

Students will learn how to draw straight line graphs in the first quadrant using function machines and tables of values to generate coordinate pairs. Ensure students are equipped with a ruler and pencil before they begin drawing their lines.

In section A, students will plot the graphs of y = x + 1, y = x + 3 and y = 2x. Learners will be provided with a function machine, a table of values for x between 0 and 3, and and three separate coordinate grids.

Next, in section B , students will plot the graphs of equations such as y = 2x + 1. The scaffolding provided decreases as the section progresses. However, a function machine, table of values, and separate coordinate grids are provided for each equation.

All straight lines have positive integer slopes and integer y intercepts.
