Fill in the Blank

Write the equation that would represent the following table (don't use any spaces):

Look at graph ->

• Slope is 2; m = 2

• y-intercept is 3; b=3

• Equation:

  y​ = 2x + 3 OR y = 3 + 2x

  ​

• Situation: I started with $3 in my piggy bank, each day I added another $2.

  ​

y = 5x + 1

The y-intercept is 1

and the slope is 5​

​​Press play and sketch the graph as Ms. Mahoney talks you through it.​ Remember 5 is the same as 5/1.
