Solving pairs of linear equations in two variables

Solve the system by substitution. 
y = 5
-6x+3y = 3

• (4,1)
• (2, 1)
• (1, 5)
• (2, 5)

Solve the following system of equations. What is the point of intersection of the two lines?

y = -3x + 4 and y = 4x - 10

• (-2, 2)

• (2, -2)

• (14, 46)

• (-6, -34)

y = x + 5

y = 6

After you type your first equation into the calculator, what button do you need to press to add an additional line?

• tab
• ctrl
• home
• Press nothing. Just cry. All hope is lost

Anika, Grace, and Michael are working on a math problem. They are trying to find the values of two variables in two equations. What does it mean when they decide to solve the system by substitution?

• They try different numbers for the variables until they find a combination that works

• They solve for a variable in one equation, and then plug what it is equal to into the other equation

• They line the equations up and subtract them from each other to eliminate a variable

• They hire a substitute to do their math for them

Solve the system using substitution method.

y = -6x

y = 6x - 12

• (1, -6)

• (1, 6)

• (-1, -6)

• (-1, 6)

Solve the system of equations:

• (0,3)
• (0,3)
• (3,0)
• (0,-3)

Solve   $2x+3y=11$  and   $2x-4y=-24$  and hence find the value of 'm' for which   $y=mx+3$  

•  $m=1$  

•  $m=2$  

•  $m=-1$  

•  $m=-2$  

y = 2x + 9

x = -3

• (-3, -33)

• (-3, 8)

• (-3, 3)

• (3, -3)
