I think the wrong number is 623.
Solution:
623 => 6 + 2 + 3 = 11
251 => 2 + 5 + 1 = 8
543 => 5 + 4 + 3 = 12
356 => 3 + 5 + 6 = 14.
Except 11 all other numbers are even.So, 623 is the wrong number.
The graph would have to look like the attachment I attached to this comment. If you can't see it then the graph will go through the y-intercept of -2 and the x-intercept of 3.
Explanation: Already we can tell that the line will go through -2 as the y-intercept. So we have to take the slope and apply it to the -2. The slope is in rise over run form. We rise 2 times. And then go to the right 3 times. We can do the same but backwards. Go down 2 times. and then go left 3 times. Do it twice in both ways and you have your line.
Answer:
Mr. Reed DATA:
rate = 40 mph ; time = x hrs ; distance = 40x miles
-----
Mrs. Reed DATA:
rate = 60 mph ; time = x - 3.5 hrs ; distance = 60x - 210 miles
Equation:
40x = 60x -210
-20x = -210
x = 10.5 hrs
x-3.5 = 7 hrs (Mr. Reed's time)
Step-by-step explanation:

The value of x should be 1 because since there's no number front of the x....so you always have to pretend that there's a invisible 1.
