Answer:
Step-by-step explanation:
Let x be the unknown number.
The sum of x and seven hundred is 
Ten thousand times this sum is 
The Y intercept is (0,5)
The X intercept is (0,-10)
9m+14=2m
9m-2m= -14
7m = -14
m= -2
to check: u need to chance the m to -2
9m - 2m= -14
9 × -2= -18
-2 × -2= -4
-18 - (-4)= -14
i think is right
