Finding the Equation of a Line from a Graph and a Table <br><br> plz help me
Leni [432]

Answer:

slope (m)= 1/2

y-intercept: (0, -1)

equation: y=\frac{1}{2}x-1

Step-by-step explanation:

slope is \frac{rise}{run\\}=\frac{1}{2}

y-intercept is where the line crosses the vertical axis (y-axis) so its (0, -1)

using point slope form:

y-y1=m(x-x1)

y-(-1)=1/2(x-0)

y+1=1/2x

y=\frac{1}{2}x-1

A hockey puck has a diameter of 3 inches and rolls on its edge for 24 rotations. How far did it roll before falling flat?
scoundrel [369]

Find the circumference of the puck using circumference = pi x diameter

Circumference = 3.14 x 3 = 9.42 inches.

For every rotation the puck would travel 9.42 inches.

Now multiply y by 24 rotations:

9.42 x 24 = 226.08 inches.

Answer: 226.08 inches
