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, )

help
do you have answer choices
no
i think you have to plug x value into the equation like y= -4.3(-3) = 12.9
and other is y = -4.3(5) -21.5
wait let me try again
yeah so you already have y itself so just and they gave you x which is -3 and 5 so plug in to the equation you get y value so then ( -3 , 12.9) and ( 5 , -21.5) you get two order pair now you use slope formula to find equation |dw:1411851506253:dw| after this now you know that slope is -4.3 so find y=intercept you can use any order pair|dw:1411851612016:dw| so that's mean the number you find is right
