If x adds 4 when y adds 12, then if x adds 1, y adds 12/4 = 3. 

Therefore, from -1 to 0, x adds 1, and y adds 3, so the answer is -7+3 = -4

You  have  the right idea, WDB22

 

y changes  by  12  when  x  changes  by 4

 

The slope is   12  / 4    =  3

 

Since (3,5)  is  on the graph

 

y = 3 (x - 3)  +  5

 

y = 3x - 9 + 5

 

y = 3x  - 4

 

When x   =  0

 

y  = 3(0)   -4

 

y = 0  -  4

 

y  = -4

 

 

cool cool cool
