Answer:

Step-by-step explanation:
.
m is the slope of the line. To find it we can do
which is the difference between the y-coordinates divided by the difference between the x-coordinates.
So:
. Now we have the slope, let's input a set of coordinates into the equation so that we can find the constant
.

- Re-arranging to get b
Now re-write the equation as we have the constants.

Y=-1/3+2 should be what you are looking for.
Answer:
12.3-7.9x
Step-by-step explanation:
8.9+3.4=12.3
-1.4x+(-6.5x)=-7.9x
