Point slope is y-y1= m(x-x1) where m is slope

Plug the values in:
y-(-8)=3(x-8)

Simplify:
y+8=3(x-8)

Write in form y=mx+b I will give brainiest to correct answer

Viktor [21]

Step-by-step explanation:

y=mx+b (m is the slope, b is the y-intercept)

To come with sope choose two points from the graph (6,20), (4,30)

Then

m=(Y2-Y1)/(X2-X1) =(4-6)/(30-20)=-1/5

b= 50 (y-intercept)

SO y=-1/5x-50

I hope this helps

What’s the correct answer

Stels [109]

$a_n=a_{n-1}+7 \ \ \to \ \ d=7 \\ \\ a_n=a_1+d(n-1) \\ a_n=17+7(n-1) \\ a_n=17+7n-7 \\ a_n=7n+10$

The answer is B. a_n = 7n+10

Create a table and graph y=x+1 demos<br>

DerKrebs [107]

Answer:

The table will be:

x y=x+1

1 2

2 3

3 4

4 5

5 6

The graph is shown in figure attached.

Step-by-step explanation:

We need to create table and graph the expression: $y=x+1$

Table is made, such that we take value of x and find value of y

You can take any values of x from negative values to positive values. I am taking values of x: 1,2,3,4,5 and find value of y.

So our table will be:

x y=x+1

1 2

2 3

3 4

4 5

5 6

Now, we will plot these value on the graph. x values will be on x-axis and corresponding y-values will be on y-axis.

The graph is shown in figure attached.

Rachel Newton scored 33 points in a recent basketball game. She scored 21 times, making several free throws worth 1 point each a

SpyIntel [72]

6

Step-by-step explanation:

Step 1:

Let Rachel scored 33 points in total

Let a be the 1 point and b be the 2 point.

a = 21 points scored by 1 point. We want to find b

Step 2:

a+b=33

b= 33-a

= 33-21

= 12

b=12 points which means 6 double points

The length of the hypotenuse of the right triangle is 25 cm, the length of one of the legs is 10 cm. What is the length of the s

Anna007 [38]

Answer:

21 cm

Step-by-step explanation:

Call the triangle ABC, with the right angle at B, the hypotenuse AC=25, and the given leg AB=10. The altitude to the hypotenuse can be BD. Since the "other leg" is BC, we believe the question is asking for the length of DC.

The right triangles formed by the altitude are all similar to the original. That means ...

AD/AB = AB/AC . . . . . . ratio of short side to hypotenuse is a constant

Multiplying by AB and substituting the given numbers, we get ...

AD = AB²/AC = 10²/25

AD = 4

Then the segment DC is ...

DC = AC -AD = 25 -4

DC = 21 . . . . . centimeters
