U7A.L3-Slope

Review of creating an equation from a table 

This is the table
for the equation x-3=y.
What does that mean?

What is the connection between the equation and the point x=0,y= -3

1. there is no connection
2. when x is 0, the y value gives us the constant for the equation
3. when x is 0, the y value gives us the coefficient for the equation

What is the connection
between the change in y in the
table and the equation y = -2x?

1. The change in y gives us the constant for the equation
2. The change in y gives us the coefficient for the variable in equation
3. There is no connection

Now let's try finding an equationt that has both a co-efficient and a constan 

What happens if
the x value in the table
is not changing by 1?

What does this look like on a graph?
