So let's convert these to improper fractions:


Then let's convert these fractions so that they have a denominator of 15 so we can better compare these numbers:


So when we have
gallons splash out, we are left with
gallons or
gallons in the tub.
if you put the points into the equation y2 - y1/x2 - x1 you'll end up with a zero in the denominator, which indicates a vertical slope. Basically the slope(m) is undefined
It's really easy to tell if your answer is going to be undefined if both the x values are the same (in this case they're both 9)
Answer:
3/4 shall be our slope.
Step-by-step explanation:
You can solve the slope by doing this formula y₂ - y₁ / x₂ - x₁ = slope.
Your coordinates:
(-4,0) and (0,3)
You have to set up your formula:
3 is the y2 and 0 is the y1
3-0 for y so far.
Now, set up the x's
0 is our x2 more known as our second x
Then our x1 is -4
0 - (-4).
Our Formula:
3-0 / 0+4
**Notice the negatives canceled to a positive due to the rule.**
3/4 shall be our slope.
You could've also risen and run starting from (-4,0) to (0,3) to get a slope of 3/4.
