Answer:

y=-\frac{3}{4}x +2

The graph in the attached figure

Step-by-step explanation:

Let

x-------> the input (independent variable)

y-------> the output (dependent variable)

we know that

The equation that represent the situation is equal to

y=-\frac{3}{4}x +2

This is a linear equation

To graph the line find the intercepts

The y-intercept is equal to the point (0,2) ---> value of y when the value of x is equal to zero

The x-intercept is equal to the point (2.667,0) ---> value of x when the value of y is equal to zero

Plot the points

Hi there!

The answer is:
y = - \frac{3}{4} x + 2

Let the input be represented by X. We can see we have to multiply it by -3/4, so we get -3/4X. To find our outcome (which is represented by y), we only have to add 2 to the function.
y (outcome) = - 3/4x (income) + 2

y = - \frac{3}{4} x + 2

The graph highlights two other points on the trend line. Use them to find another equation for the trend line shown for this sca
frutty [35]

Option A:

The equation for the trend line is y = 82x + 998.

Solution:

The points on the line are (2, 1162) and (11, 1900).

Here, x_1=2, y_1=1162, x_2 = 11, y_2=1900

Slope of the line:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

$m=\frac{1900-1162}{11-2}

$m=\frac{738}{9}

m = 82

Point-slope formula:

y-y_{1}=m\left(x-x_{1}\right)

y-1162=82\left(x-2\right)

y-1162=82x-164

Add 1162 on both sides of the equation.

y=82x+998

The equation for the trend line is y = 82x + 998.

Hence Option A is the correct answer.

The speed of sound in air on a certain stormy day is about 1130 feet per second. You see a flash of lightning striking some dist
Elina [12.6K]

Answer:

distance = 1.5 miles(approx.)

Step-by-step explanation:

given,

speed of sound = 1130 ft/s        

1 ft = 0.3048            

1130 ft/s = 0.3048 × 1130 m/s      

              = 344.424 m/s          

time = 7 second                

distance = speed × time                

distance = 344.424 × 7              

distance = 2410.968 m                    

1 m = 0.0006214 miles                    

2410.968 m =  (0.0006214 ×  2410.968) miles    

distance = 1.498 miles                        

distance = 1.5 miles(approx.)
