# Slope, x-intercept, y-intercept meaning in context

Practice determining what each of the slope, x-intercept, and y-intercept represent in a given linear relationship.

## Want to join the conversation?

• I understand the relation between the slope and the rate, but, why the rate isn't negative if the slope is -3lit/1min? Its the same?
• Well, because we need the absolute value, I reply to myself from the future haha
• why are decimals the only accepted answer on some questions, while an improper fraction is the only accepted answer on others?! I was counted wrong when I changed 14/9 to 1.56.
• Decimals are generally accepted when the number has a terminating decimal. For example, 5/4 is equal to 1.25, while 14/9 isn't equal to 1.56. If you were to divide 14/9, you would find that the five in the decimal place infinitely repeats. This is why some decimals are accepted as exact answers but not others.
• I just don't get any of it z:{
• Neither do I haha
• As per my cathing power, I have observed in a previous video about the condition when a slope is negative, and you are saying, in this question the difference of y is negative, but according to your previous video, the difference must be positive but not negative in this question
• I think that that isn't the case in this question because in the one here this shows a decrease in volume with an increase in time so it means that X and Y must have a rate of change different from each other because as the water drains the time moves on
so the difference in Y which is the liters being drained must be negative due to the water being emptied
so it is possible to have a negative change in Y
• What do the slope and y-intercept mean in the context of the problem?
• Slope is the rate of change meaning how many litres were drained at a certain period of time.
y-intecept means the time when x = 0 there was ___ litres in the tub
• is this representing slope?
• Wait so when the answers are shown, couldn't you have just divided 15 by 3?
• I am given a tria6ngle on an xy plane. A right triangle. PQR where P is (-2,6) and R is (5,0). I found the slope to be -6/7 but I cannot figure out what the y intercept is. I understand that it will be (0, ?) but I don't know how to find it given just 2 points on a line. The answer says it is 30/7 but I don't know how to get it. Please help!
