Solving Systems of Equations by Graphing

Algebra 1

We can solve thesystem of equation by graphing each equation and finding their intersection point.

y = 2x + 3
y = -3x + 4

Multiple Choice

What form do we need the equations to be in so that we can graph them?

Standard From

Slope-Intercept Form

Point-Slope Form

Any Form

One Solution

When you graph both equations they will cross in exactly ONE POINT. The INTERSECTION POINT is the ANSWER to the system.

No Solution

When you graph both equations they NEVER intersect. No intersection point means no solution.

Infinite Solutions

When you graph both equations and they overlap. When the lines overlap at every point it means they have infinite solutions. They are actually the same line.

Multiple Choice

If you graph 2 lines and they intersect at ONE point, how many solutions does the system have?

No Solution

Infinite Solutions

One Solution

None of These

Multiple Choice

If 2 lines never intersect, how many solutions does the system have?

No Solution

Infinite Solutions

One Solution

None Of These

Multiple Choice

If a system has 2 lines that overlap, meaning they share all of the same points, how many solutions does the system have?

No Solution

Infinite Solutions

One Solution

None Of These

Multiple Choice

The solution to a system of equations is any ordered pair that makes both equations true.

TRUE

FALSE

Multiple Choice

What is the first step in solving a system by graphing?

Write both linear equations in slope-intercept form

Get x by itself

Compare the slopes of both equations

Write both equations in standard form

Multiple Choice

A system of linear equations is...

Math Magic

One Equation

Always more than 2 equations

A set of 2 or more equations

Multiple Choice

If a system of linear equations has one solution, what does this mean about the two lines?

Parallel lines

the same line

Intersecting lines

Multiple Choice

How many solutions will this system have?

One

Two

No Solution

Infinitely Many Solutions

Multiple Choice

When you graph the exact same equation twice,

you will have no solution.

you will have one solution.

you will have infinite solutions.

you will graph a giraffe.

Multiple Choice

If a system of equations has no solution, what does the graph look like?

intersecting lines

parallel lines

skew lines

intersecting lines

Multiple Choice

What is the solution?
(Hint: Both lines are graphed over each other)

One Solution

No solution

Infinitely Many Solutions

Multiple Choice

This system has _____ solutions

Infinitely many
