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, )

Not multiple choice.. confused on how to find the other points

you are given the equation
y = -4.3x

and in each point, one of the variables is given, so just plug that in and evaluate.

e.g. for B
x = 5, so y = -4.3(5) = -21.5

you do the first one
-15?
