Order the steps to Solve a System of Equation by Elimination

• Put both equations in Standard Form

• Multiply the equations to make 1 variable have the same coefficient and opposite signs

• Add the equations

• Solve for 1 equation

• Substitute to find the value of the 2nd variable

Imagine Hannah and Ethan are on a treasure hunt. They found a map with a Linear Equation. To find the treasure, they must graph the line. They need to place the (a)   on the (b)   . Then, they use the (c)   to (d)   to get to the next point. Can you help them decode the map and find the treasure?

• y-intercept
• y-axis
• x-axis

• slope
• rise and run
• equation

Graph the linear equation y = -3x + 2

Hannah, Rohan, and Benjamin are playing a thrilling game of football. The Eagles, their team, are on the verge of scoring the winning touchdown. Can you guess at which coordinates (yard line, distance from sideline) did they score the winning touchdown? Remember, the solution is an ordered pair where the two lines meet. No spaces, please!

Find the solution to the system of equation by substitution. Place a point on the graph to represent the solution.

y = 3

y = 2x - 5
