Answer:

It is -6.

Step-by-step explanation:

7 + 12 is 19

b + (7 + 12) = 13

b + (19) = 13

-6 + 19 = 13

The answer you are looking for is b = -6.

There are 2 ways to find this. You could use...

  1. Add together 7 and 12 to get 19, then subtract 19 from both sides to get b = -6. OR...
  2. Subtract 12 from both sides to get b + 7 = 1, then subtract 7 from both sides to get b = -6.

Either way, you will get the same answer of b = -6. One method is just longer than the other. I hope this helps!

Please can somebody find the gradient and the coordinates of the y-intercept for the graph:
-Dominant- [34]
The equation is already is slope intercept form where you can easily point out the gradient, or the slope, and the y intercept.
y=mx+b where m is the gradient, and b is the y intercept. 
Since there is no m, the gradient is 1.
The y intercept had x=0 and y=b
b in this case is 6 
the y intercept= (0,6)
