Step-by-step explanation:
the solution is the dark area between the two lines.
the only trick would be if one of the points fell on the dotted line.

Answer:
1
Step-by-step explanation:
since the 2 functions equal each other:
-2x + 3 = 4x - 9
add -2x to both sides
3 = 6x - 9
add 9 to both sides
12 = 6x
divide by 6
2 = x
you have x, now find y, you just need to plug 2 into one of the equations instead of both bc they both equal the same anyway
-2(2) + 3
-4 + 3
-1 = y
Now we'll find x + y, input them and it's 2 + (-1), which is 1
