Determine which ordered pair is not a solution of y= -5x - 4.
(10,-52)
(7,-39)
(-7,3)
(8,-44)
I think it is (10,-52)
Pls help I always mix up graphing coordinate planes!
Disagree. Insert the x value into the equation to see if it gets you the y.
To determine which ordered pair is not a solution of the equation y = -5x - 4, you need to substitute each set of coordinates into the equation and check if the equation holds true.
Let's start by substituting the first ordered pair, (10,-52), into the equation:
y = -5x - 4
-52 = -5(10) - 4
-52 = -50 - 4
-52 = -54
Since -52 does not equal -54, this means that the equation is not satisfied by the first ordered pair.
Now let's substitute the second ordered pair, (7,-39), into the equation:
y = -5x - 4
-39 = -5(7) - 4
-39 = -35 - 4
-39 = -39
In this case, -39 does equal -39, so the equation is satisfied by the second ordered pair.
Now let's substitute the third ordered pair, (-7,3), into the equation:
y = -5x - 4
3 = -5(-7) - 4
3 = 35 - 4
3 = 31
Since 3 does not equal 31, the equation is not satisfied by the third ordered pair.
Finally, let's substitute the fourth ordered pair, (8,-44), into the equation:
y = -5x - 4
-44 = -5(8) - 4
-44 = -40 - 4
-44 = -44
In this case, -44 does equal -44, so the equation is satisfied by the fourth ordered pair.
Based on our calculations, the ordered pair that is not a solution to the equation y = -5x - 4 is (10,-52).
