Answer:

49.6

Step-by-step explanation:

A = πr2, (Pi r-squared)

A = (3.14)(8)2

A = (3.14) (64)

A = 198.4

but you need to take 1/4th of that since you are only looking at 1/4th of the circle so,

.25 x 198.4 = 49.6

Express it in slope-intercept form.

Hey there! :)

Answer:

y = 1/4x - 3.

Step-by-step explanation:

Use the slope-formula to find the slope of the line:

m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}

Plug in two points from the line. Use the points (-4, -4) and (0, 3):

m  = \frac{-3 - (-4)}{0 - (-4)}

Simplify:

m = 1/4.

Slope-intercept form is y = mx + b.

Find the 'b' value by finding the y-value at which the graph intersects the y-axis. This is at y = -3. Therefore, the equation is:

y = 1/4x - 3.
