Answer:

The answer is y-8=-0.2*(x+10)\\\\

Step-by-step explanation:

In order to determine the correct option, we have to know about point-slope form.

The point-slope form is the way that we can create linear functions from a point and a slope. The formula is:

y-y_1=m*(x-x_1)\\\\\\\\

Where:

(x_1,y_1)\\\\: Coordinates of the point.

m: Slope

Also we can get the slope from two points. The formula is:

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

(x_1,y_1)\\\\: Coordinates of the first point.

(x_2,y_2)\\\\: Coordinates of the second point.

So first we determine the slope:

P_1=(x_1,y_1)=(-10,8)\\P_2=(x_2,y_2)=(-5,7)\\\\m=\frac{7-8}{-5-(-10)}\\m=\frac{-1}{5}=-0.2\\\\\\

Finally, the correct option is:

y-8=-0.2*(x+10)\\\\

Answer:

\large\boxed{y-8=-0.2(x+10)}

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

m - slope

(x₁, y₁) - point

The formula of a slope:

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

From the table we have the points (-10, 8) and (10, 4). Substitute:

m=\dfrac{4-8}{10-(-10)}=\dfrac{-4}{20}=-\dfrac{1}{5}=-0.2

The equation of a line:

y-8=-0.2(x-(-10))\\\\y-8=-0.2(x+10)

The school fit 72 students onto 3 buses. find the unit rate for number of students per bus.
Shtirlitz [24]
The unit rate would be 24 because the unit rate is x divided by the y so 72÷3

How do you find the size of angle B?
Vitek1552 [10]

the sum of the interior angles is 180° (triangles)

it's isosceles, 2 equal sides and 2 equal angles.

you take away the given angle from 360° and you will find the sum of the 2 equal sides, you divide by 2 and you have the angle b (equal to angle C).


(180 - 72) : 2  =

108 : 2 = 54° (your answer)

-----------------------

72 + 54 + 54 = 180°

The answer is good.
