Answer:
[tex]y=\frac{1}{3} x[/tex]
Step-by-step explanation:
we need a function that when we plug the value of x, we get the given value of y.
In the coordinate point
(-9, -3)
the x and y values are:
x = -9
y = -3
so we can see that the value of y is one third of the x value (because -9/3 = -3):
[tex]y=\frac{1}{3} x[/tex]
this is also true for the secod point:
(-12, -4)
here the x and y values are:
x = -12
y = -4
again the y value is one third of the x value (because -12/3 = -4):
[tex]y=\frac{1}{3} x[/tex] ⇒ this is the equation that represents the function.
