Answer:
5 4/9 - 2 5/9= 26/9 or 2 8/9
Step-by-step explanation:
However because you can use however as “but”
Subtract the second equation from the first equation.
x = -1
Plug -1 back in to either equation and solve for y.
3(-1) + y =-10
-3 + y = -10
Add 3 to both sides
y = -7
CHECK
3(-1) -7 = -10
2(-1) -7 = -9
(-1, -7)
bearing in mind that the average rate of change = slope, and for that we can simply use two points off the table.
