Let the length of the radius = r feet.
Diameter = 2r = 2 x 6.8 = 13.6 feet
Circumference = 2
r = 2 x 3.14 x 6.8 = 42.704 feet = approx. 42.7 feet
Find slope: (-4-8)/(-4+2) = -12/-2 = 6
Y = 6x + b
Plug in a point
8 = 6(-2) + b, b = 20
Equation: y = 6x + 20
It would be y+3. This is written as an algebraic expression.
Given the slope m and a point (a,b) of a line, its equation is given by

In your case, a = -4, b = 7 and m=1/2, so we have

Answer:
This in fact would be a bar graph
Using a bar graph you can see the amount of people who like a specific type of ice cream
Hope this helps :)
Have a great day love :)
