A line is drawn so that it passes through the points (-3,0) and (1.4). What is the slope of the line?
vladimir2022 [97]

Answer: m=1

Step-by-step explanation:

For this exercise you can use the following formula for calculate the slope:

m=\frac{y_2-y_1}{x_2-x_1}

In this case you know that the given line passes through the points (-3,0) and (1.4). Therefore you can identify that:

y_2=0\\y_1=4\\\\x_2=-3\\x_1=1

Then, in order to calculate the slope of this line, you must substitute the coordinates of the points into the formula:

m=\frac{0-4}{-3-1}

Finally, evaluating, you get that the slope of this line is the following:

m=\frac{-4}{-4}\\\\m=1

Tom [10]

Answer:

0.08 minutes for a kilometer.

Step-by-step explanation:

If the track is 25 kilometers, and he runs 25 kilometers in 2 minutes, he runs a kilometer in 2÷25 minutes or 0.08 minutes which is 4.8 seconds.

I'm pretty sure the track isn't 25 kilometer or he can't run a lap in 2 minutes. But if so, the answer is 0.08 minutes.

Systems of the Body Constructed Response
fiasKO [112]

Answer:

note: there may be other possible explanations and more body systems can be involved and I can go into much greater detail

1: Nervous system signals your muscles in mouth to abduct and adduct as well as your salivary glands to produce saliva to break down the food, as well as prepare the stomach to digest the food

2: Muscular system moves muscles in mouth to break food down into smaller pieces so there is greater surface area for digestive enzymes to work on the food, then muscles in oesophagus move food to stomach, where stomach muscles churn the broken down food around to speed up digestion

3: Digestive system releases numerous digestive enzymes into the food to break down lipids, carbohydrates and proteins. Small intestines absorb nutrients into bloodstream, and large intestine absorbs water.

4: Excretory system removes excess mostly dry waste through the anus as well as urine from ureter.
