3. I bet you all are wondering: What is a linear equation?????
YIP: a Linear Equation = an equation whose graph forms a straight line.

4. What is a Linear Equation?
YIP: Linear equations are usually shown on a coordinate plane
YIP: Real life situations of linear equations:
the stock market
the payments of a car
Sports statistics

6. Let’s see if we can graph the line below…
Example 1
Graph the line y = x + 1

7. YIP: Graphing using a Table of Values
1. Draw a table
2. Choose at least 5 inputs (x values) – some negative and some positive x
rule: y = x + 1 y
Notice I chose 1 negative, 0 and 1 positive input

8. 3. Substitute the inputs into the equation to
find the outputs or y-values x
Y = x + 1 y

9. 4. Draw a coordinate plane. Be sure to label the x and y
axis and write in an appropriate scale.
5. Plot the points and connect. y x
