Sagot :
The coordinate plane shows us a positive x-axis to the right and a positive y-axis to the left. We have a scale where each square have '0.25' as the unit side. Since the library is locate 3 squares to the negative side of the x-axis, and 2 to the positive side of the y-axis, its coordinate is (-0.75,0.5).
Then, the answer to the second question is
2) The library is 0.75 unit to the left of the origin, so the x-coordinate is -0.75
With the same logic, the other texts are:
3) The library is 0.5 unit(s) up from the x-axis, so the y-coordinate is 0.5
4) The coordinates of the library are (-0.75,0.5).
5)Write the x-coordinate of the library as a fraction:
We have the x-coordinate as -0.75, which could be represented as:
[tex]-0.75=-\frac{75}{100}=-\frac{3}{4}[/tex]6)Write the y-coordinate of the library as a fraction:
We have the y-coordinate as 0.5, which could be represented as:
[tex]0.5=\frac{5}{10}=\frac{1}{2}[/tex]7) The coordinates of the library, written as fractions, are
[tex](-\frac{3}{4},\frac{1}{2})[/tex]8) What are the coordinates of the middle school?
The middle school is one square to the left and 6 squares down, which means it is in the negative direction of both axis and its coordinates have respectively the values 0.25 and 1.5.
The coordinates of the middle school are (-0.25, -1.5).
