Question 173819
Please, help me with ths equation> Write an equation for all values of x and y shown in the table. 
x y
-2 -3
-1 -5
0 -7
1 -9
----------
Notice that y decreases 2 when x increases 1; so the slope  = -2
-----------
Notice that y = -7 when x = 0, so the intercept is -7
------------
Equation:
y = -2x -7
