Question

Points A and B lie on the graph of the equation y = −4.3x.

What are the y-coordinates for each point?

Point A: (−3, ) Point B: (5, )

Answer 1

Point A has the x coordinate of -3. Plug this value into the equation to find y.


y = -4.3x

y = -4.3*(-3) ... replace x with -3

y = 12.9


So when x = -3, y = 12.9 giving the complete point A(-3, 12.9). I'll let you do point B.

Answer 2

im srry i still do get :

Answer 3

where are you stuck?

Answer 4

the whole thing lol

Answer 5

do you see how I replaced x with -3 ?

Answer 6

yeah

Answer 7

after that, I multiplied -4.3 by -3 to get 12.9

Answer 8

that's what -4.3x means

it means "take -4.3 and multiply it with some number x"

x in this case is -3

Answer 9

k

Answer 10
