Question

What is the equation of the following line?
A. y = - x
B. y = x
C. y = -4x
D. y = 2x
E. y = -2x
F. y = - x

Answer 1

(4,-2) is a point that is shown clearly on the graph, so substitute the x=4 and y=-2 into the equations to find the one which would give you the correct answer

Answer 2

A : y=-4 when x=4 which is not correct as our y is supposed to be -2

Answer 3

in that way. you check for all of them to find the right answer

Answer 4

Just put (4,-2) into the equations to see which one is valid.

Answer 5

i think its c

Answer 6

yup, it is C. :)

Answer 7

it wasnt

Answer 8

oh sorry i misread the options, it would be E.

Answer 9

it cannot be C. since -4*4 doesnt not give you -2
