NEED HELP PLEASE NOT SURE​

Answer 1

Answer:

1. Convert the x-coordinate from Mixed number to Decimal number.

2. Move over 2.5 units to the left.

3. From -2.5, move down 4 units.

4. Mark the point.

Step-by-step explanation:

By definition, a coordinate plane is formed by the intersection of two perpendicular lines: The y-axis (which is a vertical line) and the x-axis (which is an horizontal line). The point in which the y-axis and the x-axis intersect is known as "Origin" and has the following coordinates:

$(0,0)$

You have this point:

$(-2\frac{1}{2},-4)$

You can identify that the x-coordinate is:

$x=-2\frac{1}{2}$

Since it is a Mixed number you can convert it into a decimal number dividing the numerator 1 by the denominator 2 and adding the result to the Whole number part 2. Then:

 $x=-(2+0.5)=-2.5$

And the y-coordinate is:

$y=-4$

To plot the point:

- Start at the Origin.

- Move over 2.5 units to the left (because the x-coordinate $x=-2.5$ is negative).

- Then, from -2.5 you must move down 4 units (because the y-coordinate  $y=-4$ is negative).

- Mark the point.
