50.24 square inches. If the diameter is 8in, then the radius must be half the diameter, or 4. You can just plug 4 into the formula for the area of a circle [A=pi*radius^2]. When you multiply 3.14 by 4^2, you get 50.24 square inches.

Hey There!

To find the area of a rectangle we do length times width

17 is the width and 4 is the length

so area is equal to 17x4

17x4=68 so your answer would be D

(-4, -7) and (-6, 9) in slope-intercept form. Show work
BigorU [14]

Answer:

Equation of line in slope-intercept form is: y = -8x-39

Step-by-step explanation:

Given points are:

(-4, -7) and (-6, 9)

The slope-intercept form is given by the equation

y = mx+b

Here m is the slope of the line and b is the y-intercept.

m is found using the formula

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

Here

(x1,y1) = (-4-7)

(x2,y2) = (-6,9)

Putting the values in the formula

m = \frac{9+7}{-6+4} = \frac{16}{-2} = -8

Putting slope in general equation

y = -8x+b

Putting (-6,9) in the equation

9 = -8(-6)+b\\9 = 48+b\\b = 9-48\\b = -39

Putting the value of b we get

y = -8x-39

Hence,

Equation of line in slope-intercept form is: y = -8x-39
