Answer:
[tex]y = x - 5[/tex] and [tex]y = \½x[/tex]
Explanation:
Given
[tex](x,y) =(10,5)[/tex]
Required.
Select all functions that apply to this coordinate
To do this, we substitute 10 for x in each of the given functions. If y = 5, then the function includes the point
[tex]a.\ y = 3x[/tex]
Substitute 10 for x
[tex]y = 3 * 10[/tex]
[tex]y = 30[/tex]
This function does not apply because [tex]y \ne 5[/tex]
[tex]b.\ y = x^2[/tex]
Substitute 10 for x
[tex]y = 10^2[/tex]
[tex]y = 100[/tex]
This function does not apply because [tex]y \ne 5[/tex]
[tex]c.\ y = x + 5[/tex]
Substitute 10 for x
[tex]y = 10+5[/tex]
[tex]y = 15[/tex]
This function does not apply because [tex]y \ne 5[/tex]
[tex]d.\ y = x - 5[/tex]
Substitute 10 for x
[tex]y = 10 - 5[/tex]
[tex]y = 5[/tex]
This function includes the given points
[tex]e.\ y = \frac{1}{2}x[/tex]
Substitute 10 for x
[tex]y = \frac{1}{2} * 10[/tex]
[tex]y = 5[/tex]
This function includes the given points
