# 8th Grade Common Core: 8.F.3

Common Core Identifier: 8.F.3 / Grade: 8

Curriculum: Functions: Define, Evaluate, And Compare Functions.

Detail: 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.

To find the solutions for these systems of equations students must solve for x or y and then use the substitution method.

Level:

Students will find the value of one variable using division and other operations. Then they will use substitution to find the other variable and the solution.

Level:

Students will solve for the x- and y-intercepts and then use the slope formula to find the slope of the linear equations.

Level:

For each problem, students will define the slope and y-intercept. Then they graph a line to show the equation.

Level:
