NEED HELP PLEASE NOT SURE​

Answer 1

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.

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(1)/(2),-4)`

You can identify that the x-coordinate is:

`x=-2(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.
