Which set of ordered pairs are on the graph of the function y = 1/2 x - 2 ?
F (-4,0) , (6,-5 )
G (-4,0) , (6, 5 )
H (4,0) , (6,-5 )
J (4,0) , (6, 5 )
Help ? Please.
Please help, I need this ASAP.
um i think u wrote H and/or J wrongly
but its either H/J.. u wrote the answer wrongly fully
hope it helps
y = 1/2 x - 2
In the 2nd column all of the points have
x = +6
y = 1/2 x - 2
y = 1/2(6) - 2
y = 6/2 - 2
y = 3 - 2
y = 1
Therefore, none of the choices are correct (since none of the points have y = 1).
I think you have a typo because if I use x = -6
y = 1/2 x - 2
y = 1/2(-6) - 2
y = -6/2 - 2
y = -3 - 2
y = -5
So the point, (-6, -5) is on the graph.
Now you try the same with the points in the first column.
To determine which set of ordered pairs are on the graph of the function y = 1/2 x - 2, we can substitute the x-coordinates of each ordered pair into the equation and check if the resulting y-coordinate matches.
Let's go through each set of ordered pairs:
F (-4,0):
Substituting x = -4 into the equation, we get y = (1/2)(-4) - 2 = -2 - 2 = -4. Therefore, the ordered pair (-4,0) satisfies the equation.
(6,-5):
Substituting x = 6 into the equation, we get y = (1/2)(6) - 2 = 3 - 2 = 1. Therefore, the ordered pair (6,-5) does not satisfy the equation.
G (-4,0):
We already found that (-4,0) satisfies the equation.
(6,5):
Again, we previously found that (6, -5) does not satisfy the equation.
H (4,0):
Substituting x = 4 into the equation, we get y = (1/2)(4) - 2 = 2 - 2 = 0. Therefore, the ordered pair (4,0) satisfies the equation.
(6,-5):
We already found that (6, -5) does not satisfy the equation.
J (4,0):
We already found that (4,0) satisfies the equation.
(6,5):
We already found that (6, 5) does not satisfy the equation.
After going through each set of ordered pairs, we can conclude that the set of ordered pairs on the graph of the function y = 1/2 x - 2 is F (-4,0) and H (4,0).
