OpenStudy (anonymous):

ok

OpenStudy (anonymous):

OpenStudy (anonymous):

? you plug in the x value into the equation.

OpenStudy (anonymous):

do you know at all?

OpenStudy (anonymous):

the c option

OpenStudy (anonymous):

i dont know how

OpenStudy (mathmale):

You are given the linear function y=-4x. The first x-value in the table is -6, right? Substitute -6 for x in that formula, being careful to enclose the -6 with parentheses. Evaluate the resulting equation for y.

OpenStudy (anonymous):

cuz -4 x -6 = 24 -2 x -4 = 8 3 x -4 = -12

OpenStudy (anonymous):

?????????

OpenStudy (mathmale):

@noahs686 : Would you please show us how you're evaluating y when x=-6? It's important that you be involved here.

OpenStudy (anonymous):

so the answer is c

OpenStudy (anonymous):

thats why im confused

OpenStudy (mathmale):

Noah: There are just 3 input (x-) values. I'd prefer to see how you obtain the corresponding y-values before saying "yes" or "no" to Answer C. In what way do you feel confused?

OpenStudy (anonymous):

is x times or do i plug in the x value

OpenStudy (mathmale):

the first x value is -6, and yes, you do plug that into y=-4x. Use parentheses: y = -4 (-6)=?

OpenStudy (anonymous):

oh

OpenStudy (anonymous):

now i understand

OpenStudy (anonymous):

thanks

OpenStudy (mathmale):

I'm really glad. See you again! Bye, Noah.
