Graphing Equations

GRAPHING EQUATIONS

We Have Already...
Turned word problems into equations by looking for "each" and "per".


Turned equations into data tables by plugging in a number for X and solving for Y


Plotted points on a graph by looking at the X and Y axis.


Seeing straight lines on a graph slanted up (Positive) & slanted down (Negative).

Today We Are...

Putting all of this together

Connecting dots on a graph to make a line.

Look at the Y-axis line going up and down.

​The Second Number is Y

Look at the X-axis line going left & right.

​First Number is X
