Josie makes fruit punch by mixing fruit juice and lemonade in the ratio 1: 3 she needs 24 litres of punch for a party
how much fruit juice does she need?
fruit juice:
lemonade:
(in litres)


the answer is as following:

Fruit juice:6

Lemonade:18

the answer has to equal 1/3 so the answer is 6 for fruit juice and 18 for lemonade

So for this, we will be putting the equation in slope-intercept form, which is , with m = slope and b = y-intercept (aka the point in which the line crosses the y-axis)

Since it's stated that -2 is our slope, this means that -2 is the m variable.

Since it's also stated that the y-intercept is (0,3), 3 is our b variable.

Putting our equation together, it's
