Y = -2x - 4

-2x is the slope and -4 is the y intercept.

The equation of a line is y = mx + b (m is the slope; b is the y-intercept)

We are given the slope of -2 so...

y = -2x + b

We must determine b. Since they give us a point, we can sub in the x and y coords (-2,0)

0 = -2(-2) + b
0 = 2 + b
[Subtract 2 from both sides]
0-2=2-2+b
-2=b

Now, go back to the original equation (before adding coordinates in) and input b.

y = -2x-2

A class is organizing a going away party for one of their students. They spend $26.38 on decorations, $78.92 on food, and $34.50
Serjik [45]

Answer:

$9.35

Step-by-step explanation:

Simply start by adding up the total cost of each item.

$26.38 + $78.92 + $34.50

= $140.25

The total is $140.25

If 15 students want to split the cost, you’ll need to divide it by 15.

$140.25 divided by 15 = $9.35

So the total for each student is $9.35

What is the length of BC¯¯¯¯¯ ? Enter your answer in the box. units Triangle A B C with horizontal side B C. Vertex A lies above
OlgaM077 [116]

Answer: The length of BC is 22 units.

Explanation:

It is given that the Triangle ABC with horizontal side BC. Vertex A lies above side BC. Angle B and angle C are marked congruent. The length of side AC is labeled as 2x-24. The length of side AB is labeled as x-2. The length of side B C is labeled as x.

If two angles of a triangle are same it means the triangle is an isosceles triangle.

Since the angle B and C are congruent therefore the lines AB and AC are same.

2x-24=x-2

2x-x=-2+24

x=22

Since the side BC=x therefore the measure of BC is 22 units.

Find the coordinates of the midpoint of the segment.<br> MN with endpoints M (4, 10) and N(-2,-6)
Georgia [21]

Answer:

The answer is

<h2>( 1 , 2)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M  = ( \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

M (4, 10) and N(-2,-6)

The midpoint is

M = ( \frac{4 - 2}{2}  , \:  \frac{10 - 6}{2} ) \\  = ( \frac{2}{2}  \: , \:  \frac{4}{2} )

We have the final answer as

<h3>( 1 , 2)</h3>

Hope this helps you
