Question

Michelle got her uncle to sponsor her for the walk to raise money for cancer research. He said he would use the equation A = 8 + 2d, where A is the amount he will pay if Michelle walks d miles.

⦁ Identify the slope and y-intercept.

Slope:_________________ Y-Intercept: _________________

⦁ Explain the meaning of the slope and the y-intercept in this equation in terms of distance walked and the amount Michelle’s uncle will pay.

c. Sketch a graph that indicates how much her uncle will pay as a function of the distance that she walks.

Answer 1

Slope is 2 and the y intercept is 8. $8 is the amount she starts off with and then her uncle will give her an additional $2 after that for every mile she walks. (Graph in the picture)
