the table below shoes the relationship between x and f(x) for the linear function f(x) x y 0 | 10 2 | 2 4 | -6 6 | -14 what is the slope of f(x) a. -8 b. -4 c. 4 d. 8

The answer is "A," -8, because for every x, the value of y decreases by 8, thus our slope is negative 8.

^that's incorrect. use your slope formula y2-y1/x2-x1.

Take any 2 points and sub them into the formula.

so your slope is -8/2 which is -4 not -8

how'd you get that lol

Sorry, I thought the table scaled by 1s, if it did you slope is -8, but @Eureka70 is right. Sorry about not catching that.
