Fans & Medals!! 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,___)

OpenStudy (anonymous):

For each point, they give you the x-coordinate. You can plug that number in for x in the equation and simplify to figure out the y. The first x-value they give you is -3. So you have \[y=-4.3\left( -3 \right)\] Then simply multiply -4.3 by -3 and you get \[y=12.9\] So point A is (-3, 12.9). Point B will work the same way!

OpenStudy (haseeb96):

the equation is given in your question that is y=-4.3x okay? now we will first take point A in point A the x =-3 as given in question now put it in this equation y=-4.3x y=-4.3 (-3) y=12.9 for point A y =12.9 now same method apply for point b and get the Y for point B

@LOLAri do u have any question

OpenStudy (anonymous):

ok i did -4.3 -5 and got -9.3 did i do it right ?

OpenStudy (haseeb96):

@LOLAri multiply them -4.3 multiply with -5 = ???

OpenStudy (anonymous):

omg srry so i would get 21,5

OpenStudy (haseeb96):

yes this is answer

OpenStudy (haseeb96):

good job smart girl

OpenStudy (anonymous):

Where did -5 come from? The original point says (5, ) which means you do -4.3 time 5, which would give you a negative number. Should be (5, -21.5) -- unless the original point was typed wrong?

OpenStudy (haseeb96):

yes @jwhite12 he is correct there would be 5 not -5 okay?
