We see that the second definition is not a good definition. We want both parts to have the same truth value, but we see that we can have two angles created by a ray that are not equal. That means the antecedent is false but the consequence is true, which means it's not an iff statement, and a bad definition in this context.
The answer in simplest form would be 2 and 3 fifths gallons of gas.

Answer:

Step-by-step explanation:
To write an equation, use the slope-intercept equation:

M is the slope and b is the y-intercept.
First, find the slope by using the slope formula for when you have two points:

Rise over run is the change in the y-axis over the change in the x-axis. Substitute values:

Simplify parentheses (two negatives make a positive) and simplify:

The slope, m, is 4. Insert this information into the equation:

Now, take one of the points and insert into the slope-intercept formula:

Solve for b, the y-intercept. Simplify multiplication:

Add 20 to both sides and simplify:

The y-intercept, b, is 20. Insert this value into the equation:

Done.
