Bailey and Zahra ride a Ferris wheel at a carnival. The wheel has a diameter of 18m and turns at a constant speed of 3 revolutions per minute. The lowest point of the Ferris wheel is one metre above the ground. a. Determine an equation to represent the height they are above the ground in relation to time in seconds b. Include a sketch of your thinking to determine the key points of the graph c. How high above the ground will they be after 3.5 minutes?

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
