No because if it does then you had no human error and based on what your graphing it is very unlikely that when you have zero at your x axis you will also reasonably be at zero on your y axis! Hope this helps you

percent means parts out of 100 so
40%=40/100=4/10
'of' can be translated as multiply
50 times 4/10=200/10=20
$20=lunch
40%=40/100=4/10
'of' can be translated as multiply
50 times 4/10=200/10=20
$20=lunch
40% can be written in decimal form as 0.4.
If I multiply $50 by 0.4:
($50)(0.4)= $20
That means that 40% of $50 is $20.
So, you spend $20 on lunch.
If I multiply $50 by 0.4:
($50)(0.4)= $20

He has 75 chairs
The x represents the amount of chairs in each row while the number attached to the exponent shows how many rows he was able to set up with the extra chairs
9x + 3 = 7x + 19
-7x -3 -7x -3
-----------------------
2x=16 x=8
2 2
Plug 8 back into the equation and you see that it equals 75 on both sides. So that means Liam has 75 chairs to set up
