<h2>Hello!</h2>

The answer is:

The correct option is the first option:  

y=-4x+64

<h2>Why?</h2>

To write the equation of the line in slope-interception  form we need to extract all the information that we need from the graphic.

We must remember that the slope-interception form of the lines is:

y=mx+b

Where,

y, is the function

m, is the slope of the line

x, is the variable

b, is the y-axis intercept

We can find the slope using the following formula:

m=\frac{ChangeInY}{ChangeInX}

Which is for this case:

m=\frac{64}{16}=4

As we can see from the graphic, the line is decresing, so the sign of the slope "m" will be negative, so:

m=-4

We can find the value of "b" seeing where the line intercepts the y-axis.

As we can see it intercept the y-axis at:  y=64

Then, now that we already know the value of "m" and "b", we can write the equation of the line:

y=mx+b=-4x+64\\y=-4x+64

So, the correct option is the first option:

y=-4x+64

Have a nice day!

Justin opens a savings account with $4. He saves $2 each week. Does a linear function or a nonlinear function represent this sit
devlian [24]
A linear function represents this situation, because Justin’s money does not compound, and his savings increase by the same amount each week.

a circle has a center at (3,5) the point (3,8) is on the circle what is the circumference of the circle to the nearest tenth of
kogti [31]
You need to use the distance formula to find the radius of the circle.

d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2} \\  \\ d = \sqrt{(3-3)^2 + (8-5)^2} \\  \\ d = \sqrt{0^2+3^2} \\  \\ d = \sqrt{9} = 3

The radius is 3.

The circumference is 2 \pi r

= 6\pi \\  \\ =18.8
