Volgvan
<span>Let t=time Doreen travels; let r=rate of Doreen

                RATE * TIME = DIST.
        Sue | r+13      t-3       105
   Doreen |   r           t          64
 
Now solve the system:
(r+13)(t-3)=105
</span>r*t=64<span>
 
</span>r= \frac{64}{t} &#10;\\&#10;\\(\frac{64}{t} +13)(t-3)=105 &#10;\\&#10;\\64- \frac{192} {t}+13t-39-105=0&#10;\\&#10;\\13t- \frac{192} {t}-80=0&#10;\\&#10;\\ 13t^2-80t-192=0&#10;\\&#10;\\t_{1,2}= \frac{80\pm \sqrt{(-80)^2-4\times13(-192)} }{2\times13}= \frac{80\pm128}{26}  &#10;\\&#10;\\t=\frac{80+128}{26}  =8&#10;\\&#10;\\r=\frac{64}{t} =\frac{64}{8} =8<span>

Which equation is represented by the line
gulaghasi [49]

Answer:

First, we need to find the slope of this line.

Slope is defined as rise over run, or change in y over change in x. We find two  points on this line, and see that the slope is -4.

Then, we find the y-intercept, which in this case is 0.

Using slope intercept form, our answer is y=-4x

Let me know if this helps!
