please help with these problems:
write an equation in standard form, of a line having slope 5 and y-int 6
tickets to a local movie were sold at $5.00 for adults and $3.50 for students. if 280 tickets were sold for a total of $1310.00, how many adults tickets were sold

Equations:
(5,00A + 3,5S = 1310,00
( A + S = 280
A = 280 - S
Equation I:
5(280-S) + 3,5S = 1310
Go ahead!
A = adult
S = students

Slope = gradient so the gradient of the line is 5.
Formula: y = mx + b where m is the gradient & b is the y-int.
So the formula should be y = 5x + 6
Let the Adults tickets be A & Student tickets be S. The 2 equations that you can make out should be:
(1) A + S = 280 and (2) 5A + 3.5S = 1310
After solving the 2 equations your answer should be A = 220 & S = 60.

1. Standard form is y = mx + b
First: replace 5 with "m" and replace 6 with "b" in the formula >
y = 5x + 6
P.S. "m" represents the slope and "b" represents the y-intercept
