Answer:

Step-by-step explanation:
The general equation of a line: 
In our case <em>a</em> is given

Now we plug in for <em>a</em> and we get:

Now we plug in our coordinates into this equation and we solve for <em>b</em>

So the equation of the line is 
I hope this helps you
a= -5t+30
5t=30-a
t=30-a/5
5 <30-a/5 <7
5.5 <30-a <7.5
25 <30-a <35
25-30 <30-a-30 <35-30
-5 < -a <5
5>a>-5
