Solving Systems by Graphing

Front

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

Back

Write both linear equations in slope-intercept form.

Front

Which of these represents point-slope form of a linear equation?

Back

y - y₁ = m(x - x₁)

Front

What is the solution to the system of equations graphed by Buzz?

Back

(1, -4)

Front

How many solutions will a consistent system of equations have?

Back

One.

Front

What is the solution to the system of equations if the answer is (-2, 2)?

Back

(-2, 2)

Front

What is slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean if two lines are parallel in a system of equations?

Back

They have no solution because they never intersect.

Front

What is the graphical representation of a system of equations?

Back

The intersection point(s) of the lines representing the equations.

Front

What does it mean if a system of equations has infinitely many solutions?

Back

The lines are coincident, meaning they lie on top of each other.

Front

How do you find the x-intercept of a linear equation?

Back

Set y = 0 and solve for x.
