Label the slope and y intercept​
Amanda [17]
The slope is 3/2 and the y-intercept is 0.

Slope is rise/run or y/x. The y-intercept is the value of y when the value of x is 0.

A​ 0.8-liter bottle of Mexican wine costs 90 pesos. At that​ price, how much would a​ half-gallon jug of the same wine cost in​
algol13

A half-gallon jug of the same wine would cost $10.82

<h3>How much would a​ half-gallon jug of the same wine cost in​ dollars?</h3>

The given parameter is:

0.8-liter bottle = 90 pesos

As a general rule of conversion

1 liter = 0.26 gallon

This means that:

0.8 liter = 0.8 * 0.26 gallon

Evaluate

0.8 liter = 0.208 gallon

Substitute 0.8 liter = 0.208 gallon in 0.8-liter bottle = 90 pesos

0.208 gallon = 90 pesos

Divide both sides by 0.208

1 gallon = 432.69 pesos

Divide both sides by 2

0.5 gallon = 216.35 pesos

1 peso = 0.050 United States Dollar

So, we have:

0.5 gallon = 216.35 * $0.05

Evaluate

0.5 gallon = $10.82

Hence, a​ half-gallon jug of the same wine would cost $10.82
