Describe how the coordinates of an ordered pair are used to plot a point on a coordinate plane ?
kodGreya [7K]
The line going from side to side is the x coordinate and the first number in the ordered pair the second number is the y coordinate which is the line going up and down. You take the first number and go to it on the line going side by side then you stay there and go up or down from that position how many spaces the second number is.

The integers that make the linear equation false are:

3, 78, and 126

We found that by evaluating the equation in all the options.

<h3>Which integers make the equation false?</h3>

Here we have the linear equation:

8m - 15 = 5m + 63

And the possible solutions are:

S: {3, 26, 78, 126}

To see which of these integers make the equation false, we can replace the value of m by the given values and see when the equation is false (the number in the left is different to the one in the right).

if m = 3

8*3 - 15 = 5*3 + 63

9 = 78    this is false.

if m = 26

8*26 - 15 = 5*26 + 63

193 = 193  this is true.

if m = 78

8*78 - 15 = 5*78 + 63

609 = 453  this is false.

if m= 126

8*126 - 15  = 5*126 + 63

993 = 693  this is false.

So the integers that make the equation false are:

3, 78, and 126.
