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:
[tex](0,0)[/tex]
You have this point:
[tex](-2\frac{1}{2},-4)[/tex]
You can identify that the x-coordinate is:
[tex]x=-2\frac{1}{2}[/tex]
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:
[tex]x=-(2+0.5)=-2.5[/tex]
And the y-coordinate is:
[tex]y=-4[/tex]
To plot the point:
- Start at the Origin.
- Move over 2.5 units to the left (because the x-coordinate [tex]x=-2.5[/tex] is negative).
- Then, from -2.5 you must move down 4 units (because the y-coordinate [tex]y=-4[/tex] is negative).
- Mark the point.
