Answer 1

@Vocaloid

Answer 2

pick two points then find the rise/run

Answer 3

has a rise of 1 and a run of -3

so slope = (-1/3)

then find the y-intercept by finding the value of the graph when x = 0

Answer 4

your equation should look like f(x) = mx + b except with m replaced with the slope and b replaced with the y-intecept

Answer 5

f(x)=-1/3x + -1?

Answer 6

good, but I would just change the +- to a -

so f(x) = (-1/3)x - 1
