Hi! I'm happy to help!

Point slope form states that y-y_{1}=m(x-x_{1}). m represents your slope (rise/run) and y_{1} and x_{1} represent your first y and x points, and y and x represent your second y and x points. We already have our equation here:

y - 4 = 1/4(x- 8)

Now, let's dive into what slope-intercept form is. Slope intercept form states that y=mx+b. m represents our slope, b represents our y intercept, y represents a y point, and x represents the corresponding x point.

Since we know our m, we can solve for b, by using our other numbers. Let's use our first set of coordinates.

4=1/4(8)+b

4=2+b

2=b

Now our second set to double check:

2=1/4(0)+b

2=0+b

2=b

We know that b must equal 2, so our equation must be y=1/4x+2, which is  option 3.

<u>You should pick option 3.</u>

<u>(y-intercept is where the line hits the y-axis(when x=0). We could've used our second coordinates (0,2), where x equals 0 to know that 2 is the y-intercept (b). This shortcut only works on specific problems though.)</u>

I hope this was helpful, keep learning! :D

Find the exact perimeter of triangle ABC.
Lady_Fox [76]

Perimeter of triangle ABC is 6 \sqrt{5}+6 m.

Solution:

Given data:

AB = 3 \sqrt{5} m

BC = 3 \sqrt{5} m

CA = 6 m

Perimeter = Sum of all the sides

Perimeter of triangle ABC = AB + BC + CA

                                           =3 \sqrt{5}+3 \sqrt{5}+6

                                           =6 \sqrt{5}+6 m

Perimeter of triangle ABC is 6 \sqrt{5}+6 m.

3. What is the average (arithmetic mean) of all the multiples of ten from 10 to 190 inclusive?
viktelen [127]
Hello!

The average mean (arithmetic mean) of all the multiples of ten from 10 to 190 inclusive would be C. 100.

Explanation:

10 and 190 inclusive would mean that there are 19 terms.

To find the arithmetic mean, we must add all the numbers and divide by the amount of numbers.

If you add up all the terms, you will get 1,900. Now, divide that by the number of terms.

1,900 ÷ 19 = 100

Therefore, your answer is C. 100.

Have a wonderful day!

Tanzania [10]

Answer:

The type of sampling method Dr. Lawrence going to use is Quota Sampling.

Step-by-step explanation:

In quota sampling participants are chosen nonrandomly so it is not a representative sampling method.  In this case Dr.Lawrence has a quota of 15% for first-time students and 85% for returning, so the survey she is conducting is non-random. The sampling method she should use is Quota Sampling.
