All points on a given line have their y-coordinate as 9. what is the equation of this line? a. x + y = 9 b. x – y = 9 c. x = 9 d. y = 9 e. x + y = 0

D. y = 9 because it has a complete zero slope while the y-intercept of the equation is 9, so the equation is y = 9.

It would be D.

hope it helps :)

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
