In the graph above, what is r in terms of t?

The equation r in terms of t is

We have to find, The value of r in terms of t.

Let, the linear equation is,

The point on the graph is (2, t) and (r, 5).

Substitute the point in the linear equation,

Substitute the point (2, t) in the equation,

And Substitute the point (r, 5) in the equation,

On dividing both the equation,

The r in terms of t is,

Hence, The equation r in terms of t is

D

Step-by-step explanation:

The line in its general form is y = ax+b, but in this case you can observe that b=0. So we can substitute A and B in this equation y=ax, and then eliminate a.

A: t = 2a

B: 5 = ra

rewriting the first to isolate a:

a = t/2

rewriting the second to isolate r:

r = 5/a

Now substituting the first in the second:

r = 5/(t/2) = 5 * 2/t = 10/t

answer D!

the answer is: the length is 5/6 yards.
