I think that you are correct
I will but the picture is blurry
(2,7)
(6,12)
(10,17)
Some moderator deleted my response for some reason. I did it mentally.. but I guess I'll show proof.
1) (2,7)
-4y = -5x - 18
-4(7) = -5(2) - 18
-28 = -10 -18
-28 = -28
2) (6,12)
<span>-4y=-5x-18
</span> -4(12) = -5(6) - 18
-48 = -30 - 18
-48 = -48
3) (10,17)
4y=-5x-18
-4(17) = -5(10) - 18
-68 = -50 - 18
-68 = -68
See the pattern? 2,6,10 and 7,12,17?
Done with substitution and trial and error :3333
<u>Answer:</u>
50 miles per hour
<u>Step-by-step explanation:</u>
Step 1: We subtract 600 from 1000. That gives us 400 miles for the second day.
Step 2: Now we divide that by 8, giving us 50 miles per hour. We have our answer!
