An ordered pair of the function d(t) = 35t is what

So it is input is t and output is d(t)
so in normal terms it could be like this
y=mx
y is output
x is input

y is dependend variable
x is independent variable
basically it is
y=35x

normally ordered pairs are written as
(x,y)
so just subsitute values for x and get values for y ( or in this case the point is (t,d( so subsitute values for t and get outputs of d(t))

ex.
if you put 1 for t then you get
d(1)=35(1)
d(1)=35
so the point would be (1,35)
if t=0
d(0)=35(0)
d(0)=0
another point would be (0,0)
