Writing Equations from Tables Ordered pair ( x, y) Slope = rise over run Y- intercept point is (0,b) Slope intercept form y = mx +b

Ways to find slope Option 1 Draw a graph and make a triangle to determine the rise over the run

Ways to find slope Option 2 Determine ratio for the change in y to the change in x x y -1 1 -4

Ways to find slope Option 2 Determine ratio for the change in y to the change in x Given ( 0 , -1 ) and (1, -4) M = y – y x - x

Plug in the values y=mx+b MONDAY’s Notes Write the equation Find m and b. m = b = Plug in the values y=mx+b

Writing Equations from Tables x y -2 5 -1 2 1 y = mx +b

Writing Equations from Tables Find m and b. m = b = Plug in the values y=mx+b x y 4 1 -2 2 -8

Writing Equations from Tables Find m and b. m = b = Plug in the values y=mx+b x y 3 2 1 -1

Writing Equations from Tables Find m and b. m = b = y=mx+b Plug in the values x y -4 -2 -3

Writing Equations from Tables Find m and b. m = b = Plug in the values y=mx+b x y -2 2 -1 1

So where do we see examples of graphs, tables and equations like this in the real world?
