Find the point-slope equation for the line that passes through the points (30,2) and (15,-28) use the first point in your equati
Sladkaya [172]

Answer:

y=2x-58

Explanation:

In order to write our point-slope formula (y=mx+C format), we first need to figure out the slope (m). To figure out the slope, we divide the change in y by the change in x between the two points (rise/run). The rise is 30 (2-(-28)) and the run is 15 (30-15). Therefore the slope is 2 (30/15)

This gives us:

y=2x + c

Now to figure out C (which will be the y-intercept of the graph) we substitute in the values from one of the points. So our x=30 and our y=2:

2=2(30) + c

2=60+c

2-60=c

-58=c

So now we know that our C (constant) is - 58.

Hence our point-slope formula is:

y=2x-58

Which you can test with the other point:

-28=2(15) - 58

Hope this helped!

Find two consecutive integers whose sum is 77​
Semenov [28]

Answer:

<h3>                 38, 39 </h3>

Step-by-step explanation:

The difference between two consecutive integers is 1

So if

x  - the smaller number

then

x+1   - the larger number

x + x+1 = 77

  -1          -1

2x = 76

÷2    ÷2

 x = 38

x+1 = 38+1 = 39

Solve for a.
Tanya [424]

Final Answer: All Real Numbers

Steps/Reasons/Explanation:

Question: Solve for a. 4(a + 3)=12 + 4a.

<u>Step 1</u>: Expand.

4a + 12 = 12 + 4a

<u>Step 2</u>: Cancel 4a on both sides.

12 = 12

<u>Step 3</u>: Since both sides equal, we would have infinitely many solutions.

~I hope I helped you :)~
