Unit 2, Lesson 14

Making More New, True Equations

Extra Support Materials for Algebra 1

14.1

Warm-up

Match each equation with its graph. One graph does not match with any of the equations.

<p>Y=7 graphed on Coordinate plane </p> — A

<p>Graph of x=7 on coordinate plane </p> — B

<p>Line graphed on coordinate plane. X intercept = 7. Y intercept =7. </p> — C

<p>Graph of line. Passes through -2 comma-10 and origin </p> — D

14.2

Activity

Rewrite each expression by combining like terms.

14.3

Activity

For each system of equations:

Solve the system of equations by graphing. Write the solution as an ordered pair.
Write an equation that would be represented by a vertical or horizontal line that also passes through the solution of the system of equations.
Graph your new equation along with the system.
