<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>
<span>
Doreen: rate = 8 mph, time = 8 hours
Sue: </span>rate = 21 mph, time = 5 hours<span>

Answer:
The answer to your question is y = 4/6x - 4
Step-by-step explanation:
Data
m = 4/6
P (0, -4)
slope-intercept form = ? y = mx + b where m is the slope and
b is the y-intercept
Formula
y - y1 = m(x - x1)
Substitution
y - (-4) = 4/6(x - 0)
Simplification
y + 4 = 4/6x
Result
y = 4/6x - 4
slope = 4/6 y-intercept = -4
