Question

Points A and B lie on the graph of the equation y= -4.3x what are the y coordinates for each point?

Answer 1

No,sorry.

Answer 2

PoinyA= -3,2 and Point B = 5,1 ?

Answer 3

f(x) = -4.3x

f(x) = y

substitute x with a value then you'll get the y.

Answer 4

they tell you the relation between y and x. Given either of them, you can determine the other, as y is just -4.3 times the x value.

the points you gave have y values
A(x , y) = (-3 , 2)

but do not work in the equation, 2 = -4.3(-3)
