Question

Grace is comparing cell phone plans. A prepaid phone plan costs $0.20 per minute and What is the y-intercept of the function f(x) = –negative StartFraction 2 Over 9 EndFraction.x + ?

–negative StartFraction 2 Over 9 EndFraction.
–negative StartFraction 1 Over 3 EndFraction.
StartFraction 1 Over 3 EndFraction.
StartFraction 2 Over 9 EndFraction.

Answer 1

In the equation f(x) = –2/9x + ?, the coefficient of the x variable is -2/9. However, the value of the y-intercept, represented by the question mark (?), is unknown and cannot be determined from the given information.

To find the y-intercept, we need to know the value of f(x) when x is equal to 0. However, without the value of the question mark (?), we cannot determine the specific y-intercept in this case.
