WHAT IS THE EQUATION OF THE LINES IN SLOPE -INTERCEPT FORM ?

y = 3x

Step-by-step explanation:

formula = y = mx + b

m = slope

b = y-intercept (but we dont see it here, it goes through the point 0)

To find slope do rise over run ( y/x)

r/r = 3/1 = 3

The slope is 3

y = 3x or y = 3x + 0 (same thing)

Hope this helped!

Have a day!

the answers c

3

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!
