Which ordered pair is a solution of the equation y = 3x? how do I do this im confused?

It probably didn't match because you put them in wrong. (x,y) -30=3*-10

What you do is Substitute the number in for the letter. A point on a line is represented by (x,y). The x being the number of spaces moved left or right on the graph and the y being how many you move up or down. In this case the x choices are -2, -8, and -10 and the y choices are -9, -18, -3, and -30. You must keep the ordered pairs together though. So plug in one ordered pair, the (x,y) into the problem. Ex: (-2, -9). -9 = 3 (-2). Then simplify. -9 = -6. That is incorrect so do the same with the other ordered pairs. When you do that you find (-10, -30) fits perfectly. :)

First things first, an ordered pair is written as (x,y). To find a pair which satisfies this equation, plug the x value of the ordered pair into y=3x in the x position. If the y value you get doesn't match what is given in the ordered pair, try another.

In this case, the answer is (-10,30)

y=3*-10=-30

y=-30 when x is -10. This satisfies the equation.

y=3x

no matter what is here the x coordinate will be the first in the ordered pair

-30=3(-10)

a million. L= W +2 < first assertion 2L + 2W= 36 <perimeter plug L's value from the 1st equation, w+2, into the 2nd equation: 2(w+2) + 2W = 36 resolve for w... optimistically you're able to do this. (it incredibly is 8) then plug w back into the 1st equation: L= (8) + 2 subsequently, L = 10 2. Graph y=3x+a million -right away line w/ slope of three; crosses y-axis at a million -then shade below for decrease than Graph y= -2x - 4 -right away line slanting left w/ slope of -2; crosses y-axis at -4 -shade above graph for greater desirable than elect a element in section it is shaded by utilising the two graphs 3. area a million: resolve each and each equation for y: y= x/2 & y= -5x/2 +12 graph each and each and locate intersection area 2: resolve for y in first equation... y= x/2 and plug it into 2nd equation: 5x+2(x/2)= 24 resolve for x area 3: ?

x=- 10

y = -30

y = 3x means the y coordinate is 3 times the x coordinate, which is true for (-10, -30)

(-10, -30) should be your answer. Remember that the left number is your x coordinate and the right number is the y coordinate so you just substitute and you should get -30 = -30 when you plug those two in.

each ordered pair is (x,y) so plug in for each ordered the x in the equation and y into the equation until one of them makes it true. that will be the solution.
