Matching Tables, Graphs & Equations

A little review…

1. X 0 1 2 3

Y 4 6 8 10

Write the equation for this table. *How much do you get for “showing up?” *How much do the “y” values change?

y = 4 + 2x

2. X 0 1 2 3

Y -6 -3 0 3

Write the equation for this table. *How much do you get for “showing up?” *How much do the “y” values change?

y = -6 + 3x

3. X 0 1 2 3

Y 7 5 3 1

Write the equation for this table. *How much do you get for “showing up?” *How much do the “y” values change?

y = 7 - 2x

4. X 0 1 2 3

Y -2 -6 -10 -14

Write the equation for this table. *How much do you get for “showing up?” *How much do the “y” values change?

y = -2 - 4x

5. Write an equation for this graph. *How much do you get for “showing up?” *How much do the “y” values change?

y = -2 + 1x

6. Write an equation for this graph. *How much do you get for “showing up?” *How much do the “y” values change?

y = 1 + 3x

7. Write an equation for this graph. *How much do you get for “showing up?” *How much do the “y” values change?

y = 1/2x

Match the table to the equation.
