Write an equation that represents the line (use exact numbers)
scZoUnD [109]

Answer:

y = x + 6

Step-by-step explanation:

Given

The attached graph

Required

Find the equation of the graph

First, we have to get the coordinates of any two points on the graph;

Point 1:

When x = 0; y = 6

Point 2:

When x = -6, y = 0

So, at this stage;we have two coordinates

(x_1,y_1)(x_2,y_2) = (0,6)(-6,0)

Next is to determine the slope of the line using the following formula

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

Substitute (x_1,y_1)(x_2,y_2) = (0,6)(-6,0)

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

m = \frac{0 - 6}{-6 - 0}

m = \frac{- 6}{-6}

m = 1

Next is to determine the equation using slope formula

m = \frac{y - y_1}{x - x_1}\ or\ m = \frac{y - y_2}{x - x_2}

using

m = \frac{y - y_1}{x - x_1}\ where\ m = 1\ x_1 = 0\ and \ y_1 = 6

1 = \frac{y - 6}{x - 0}

1 = \frac{y-6}{x}

Multiply both sides by x

x * 1 = x * \frac{y-6}{x}

x = y - 6

Add 6 to both sides

x + 6 = y - 6 + 6

x + 6 = y

y = x + 6

<em>Hence, the equation of the line is </em>y = x + 6<em></em>

Find the population density round to the nearest tenth
Svetlanka [38]

In order to accomplish that trick, we would need two pieces
of information that you haven't given us:

1).  The area you're interested in

2).  The population inside that area

With that information, the population density is

           (population in the area) divided by (the area of the area) .

The youth soccer team is fundraising by washing cars. They paid $84.55 for supplies. If they charge eight dollars per wash, how
zmey [24]

Answer:

about 49 cars

Step-by-step explanation:

if they want to remake the money they spent then it would be about 49 cars cause $384.55 divided by 8 is 48.06875 , so if you round it , its about 49 cars to wash. but if thye dont want to remake the money they spent then it would be about 39 cars , cause 300 divided by 8 is is 37.5 but they cant just wash half a car.
