Which line contains the point (1,-3)

Rzqust [24]

There are infinitely many lines that have the point (1,-3).

A line can be expressed as:

y=mx+b, where m=slope and b=y-intercept..

Our only restriction is that it passes through (1,-3) so

-3=1m+b

So as long as the sum of the slope and the y-intercept is equal to -3, that is one of the infinite number of lines that passes through (1, -3)

So we could also say b=-3-m then our infinite lines are:

y=mx-3-m, now any real value of m creates a specific line that passes through the point. ie the first few are

y=x-4, y=2x-5, y=3x-6 or even y=x√2-3-√2

30 pts. Harrison has 2500 kg of sand delivered to a construction site every day. About how many tons of sand does he have delive

Ymorist [56]

There are 7 days to a week, so 4 weeks = 4 * 7 = 28 days.

28 days x 2,500 kg per day = 70,000 total kgs.

Divide total kgs by kgs per ton:

70,000 total kgs / 907.2 kg per ton = 77.16 tons , round the answer to 77 tons.

Answer:

y=3/4x+7

Step-by-step explanation:

You want to find the equation for a line that passes through the point (-4,4) and has a slope of 3/4. 

First of all, remember what the equation of a line is: 

 

y = mx+b 

Where: 

m is the slope, and 

b is the y-intercept 

To start, you know what m is; it's just the slope, which you said was 3/4. So you can right away fill in the equation for a line somewhat to read: 

y=3/4x+b. 

Now, what about b, the y-intercept? 

 

To find b, think about what your (x,y) point means: 

(-4,4). When x of the line is -4, y of the line must be 4. 

Because you said the line passes through this point, right? 

Now, look at our line's equation so far: . b is what we want, the 3/4 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-4,4).

 

So, why not plug in for x the number -4 and for y the number 4? This will allow us to solve for b for the particular line that passes through the point you gave!. 

 

(-4,4). y=mx+b or 4=3/4 × -4+b, or solving for b: b=4-(3/4)(-4). b=7.

hope this answers your question sorry it's soo long i just like writing long stuff have a great day!!

Step-by-step explanation:

So I Subtracted 20 - 12.98 And Got the Answer $ 7.02

To Add Or subtract Decimals Here's what you can do to find your Answer

Line up the numbers vertically so that the decimal points all lie on a vertical line.

Add extra zeros to the right of the number so that each number has the same number of digits to the right of the decimal place. Step 3: Subtract the numbers as you would whole numbers.

Hope this Helps!!

Have a great day!!!
