if a circle of radius 13 is made to roll along the x-axis, what is an equation for the path of the center of the circle?

OpenStudy (hunus):

|dw:1367354040032:dw| So the path of the center of the circle is a straight line that is 13 units above the x-axis

OpenStudy (hunus):

Since there is no rise of the slope (m = 0) the equation will be of the form \[y = mx + b = 0x + b = b\] \[y=b\] So what would b be in this scenario?

OpenStudy (anonymous):

13?

OpenStudy (hunus):

Yup

Thank you!

OpenStudy (hunus):

Yup :)
