Answer 1

Answer:

You can you the $y=mx+b$ formula by substituting $16=3(5)+1$

Step-by-step explanation:

g = groups of tennis balls

one can can hold 3 tennis balls

plus we have 1 let over

so you can use an equation  like this:

$3g+1=$ number of tennis balls

So we know how many tennis balls fit into one can and we know the left over amount:

$3(5) + 1 = 16$

She had 16 tennis balls in total.

Its essentially a y=mx+b equation but replace: x with the number of cans, m with the amount of tennis balls that goes into each can, and b with the left over tennis balls.

$y=mx+b\\y=3g+1\\y=3(5)+1\\y=15+1\\y=16$

And y would be the amount of tennis balls we have in total.
