Y= -1/3x +2.5

step-by-step explanation:

first I reconfigured the given equation: x+3y=15

-x+x+3y=15 -x  Subtracted x from both sides

3y=15-x            Simplify

3y/3=15-x/3      Divide both sides by 3

y=-1/3x+3          Simplify

I turned it into y=-1/3x+5

then I translated the line up and down to find what point crossed (6,1)

The proper value for B in y=mx+b was 2.5

Try using Desmos online calculator it really helps

Hope this helped :)

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
