Which of the following is a solution to the equation y=3x - 1? a. (4, 1) b. (2, 5) c. (4, 3) d. (0, -3) 2. which equation matches the statement "the sum of -4x and 2 is 9"? a. -4x + 2 = 9 b. -4x + 9 = 2 c. -4x(2) = 9 d. -4x - 2 =9 3. solve x - 6 = -18 a. x = -24 b. x = -12 c. x = 12 d. x = 6 4. solve 4x + 3 = 47 a. x= 11 b. x= 40 c. x= 44 d. x= 50

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.

edit: i meant
