Systems of Equations - Graphing

What is a system of equations?

• A line in the form y=mx+b

• A point that follows (x, y)

• A group of equations with the same variables

• A set of lines that describe a relationship between x and y

How do you solve a system of equations graphically?

• Graph both lines and look for the intersection point(s).

• Graph both lines and look for the y-intercepts

• Graph both lines and compare the differences in their slopes

• Graph both lines and find the difference in the y-values and x-values.

How many solutions will this system have?

• No Solution
• Infinitely Many Solutions
• No Clue
• One solution
