How do you solve a system of equations with a graph?

To solve a system with a graph, you just look for the point where the two lines cross or intersect.

100

What is the first step when solving a system of equations using substitution?

The first step would be to isolate one of the variables and then substitute it into the other equation.

100

Simplify by combining like terms:

2x + 3x

What is the fastest animal in the world?

A cheetah! They can go from 0 to 60 miles per hour in less than three seconds.

200

What is the largest city in the US?

It depends how you count! The city with the largest area is Jacksonville, FL (875 square miles). The city with the largest population is New York City (8.4 million people).

How many solutions will the system in this graph have?

This system will only have one solution.

200

Simplify using substitution:

2x + 1, when x = 2

2x + 1

2(2) + 1

4 + 1

200

Simplify by combining like terms:

2x + 3x + 1 - 2

(2x + 3x) + (1 - 2)

5x - 1

300

Simplify using substitution:

3x + 1, when x = 2y

3x + 1

3(2y) + 1

6y + 1

300

Simplify by combining like terms:

2x + 1 + 3x + 3

(2x + 3x) + (1 + 3)

5x + 4

What is the largest country in the world by area?

Russia! It has a total area of 6,601,665 square miles.

400

How many solutions will a system of parallel lines have?

It will have zero solutions because the two lines will never cross.

400

Simplify using substitution:

4y + 1, when y = x + 2

4y + 1

4(x + 2) + 1

4x + 8 + 1

4x + 9

400

Simplify by combining like terms:

2x + 1 + 3x + y - 1

(2x + 3x) + (y) + (1 - 1)

5x + y + 0

5x + y

There are two different types of frogs! They each only grow to about 7 mm long.

500

What is the smallest country in the world?

Vatican City! It has a total area of less than one square mile.

500

What is the solution to the system of linear equations?

This system would have infinite solutions (all the points on the line would be solutions).

500

Find the solution to this system using substitution:

y = 2x

3x + y = 5

3x + 2x = 5

5x = 5

x = 1

y = 2(1)

y = 2

(1,2)

500

Simplify by combining like terms:

2x + x - 1 + y - 3 - x

(2x + x - x) + (y) + (-1 - 3)

2x + y - 4
