Substitution Method Practice Already in Y Intercept

What is the value of the x-coordinate to the solution to this system of linear equations? 2x + 3y = 15 and -x + 3y = 3

What is the solution to this system of equations?

Write your answer in this form: ( , )

What is the value of the y-coordinate in this system of linear equations? 6x + 10y = -32 and 6x + 9y = -27

Solve the system of equations.
y = 4x+1
3x + 2y = 13

• (1, 5)

• (5, 1)

• (0.25, 2)

• ∅

What is the meaning of the y-intercept?

• The hamburger will cost $1.90 without any toppings.

• The hamburger will cost $1.40 without any toppings. 

• The cost of the hamburger is $1.90 with one topping

• The cost of the hamburger doesn't change no matter how many toppings there are.

Solve for x and y. y = 2/3x - 2 y = -x + 3

Write the answer in (x,y) form

A large pizza at Palanzio’s Pizzeria costs $6.80 plus $0.90 for each topping. The cost of a large cheese pizza at Guido’s Pizza is $7.30 plus $0.65 for each topping. Which system of equations could be used to find the number of toppings when both companies cost the same amount?

• y = 6.80 + .65x
  y=7.30+.90x

• x + y = 6.80
  x + y = 7.30

• y = 6.80+.90x
  y = 7.30 + .65x

• y + .90x = 6.80
  y + .65x = 7.30

Solve the following system of equations using the substitution method:

Write the solution in (x,y) form

• (3, 1)

• (1, 3)

• (-3, 1)

• (3, -1)

Solve the system of equations by substitution.
y = -4x + 5
y =  3x - 16

• (-3, -25)

• (3,-7)
