Determine which ordered pair is a solution of y = 2x - 3
A. (-2, 7)
B. (0, 3)
C. (-4, -11)
D. (5, -7)***
Please help!
Also could someone please help with this one too:
On which of the following lines does the point (7, 1) lie?
A. y - 5x =4
B. y = x - 10
C. y = -4x + 3***
D. y = x + 8
#1 Nope.
2*5-3 ≠ -7
#2 Nope.
1 ≠ -4(7)+3
In fact, I suspect a typo. None of the choices works.
The second one is B
I'm not good with coordinate planes and these types of graphs so...
thanks??
To determine which ordered pair is a solution of the equation y = 2x - 3, we need to substitute the values of x and y from each ordered pair into the equation and check if the equation holds true.
Let's go through each option:
A. (-2, 7)
Substituting x = -2 and y = 7 into the equation:
7 = 2(-2) - 3
7 = -4 - 3
7 = -7 (The equation does not hold true)
B. (0, 3)
Substituting x = 0 and y = 3 into the equation:
3 = 2(0) - 3
3 = 0 - 3
3 = -3 (The equation does not hold true)
C. (-4, -11)
Substituting x = -4 and y = -11 into the equation:
-11 = 2(-4) - 3
-11 = -8 - 3
-11 = -11 (The equation holds true)
D. (5, -7)
Substituting x = 5 and y = -7 into the equation:
-7 = 2(5) - 3
-7 = 10 - 3
-7 = -7 (The equation holds true)
Therefore, the ordered pair (5, -7) is a solution to the equation y = 2x - 3.
