Answer:
X=5 (Or (5,0))
Step-by-step explanation:
The Y intercept is when X=0
The X Intercept is when Y=0
Our equation is y=-4200x+21000
So let's rewrite it... First subtract 21,000 (Also, remember Y is 0)
0-21000=-4200x
-21000=-4200x
Now to get X alone, divide -21000 by -4200
This will give us 5=x, which is the same as x=5. There is your answer!
