PAGE 133 #2 How many solutions does the system have?

• One solution because the linear functions intersect at one point on the graph.

• Infinitely Many solutions because the linear functions have the same slope and y-intercept meaning they are the same lines.

• No Solution because the linear functions have the same slope but different y-intercepts meaning they are parallel lines.

PAGE 135 #5: Here is a system of equations

-x+6y=9

x+6y=-3

Should you use subtraction or addition to solve the system?

• Addition to eliminate the x variable, then solve for y.

• Subtraction to eliminate the y variable, then solve for x.

• Both addition and subtraction would work depending on which variable you want to eliminate.

PAGE 136 #7: Here is a system of linear equations:

6x-y=18

4x+2y=26

Select ALL the steps that would help to eliminate a variable and enable solving.

• a. Multiply the first equation by 2, then subtract the second equation from the result.

• b. Multiply the first equation by 4, the second equation by 6, then subtract the resulting equations.

• c. Multiply the first equation by 2, then add the result to the second equation.

• d. Divide the second equation by 2, then add the result to the first equation.

• e. Multiply the second equation by 6, then subtract the result from the first equation.
