To get the result we have to transform given formula into y=ax+b form.
Lets do this
5x+3y=6 /-5x (subtract 5x both sides)
3y=-5x+6 /:3 (divide both sides by 3)
y=

In form y=ax+b we know that a is slope and b is y intersect. We can read from our transformed equation that slope a=

and its the result
Answer:B
Step-by-step explanation:
Answer:
162km
Step-by-step explanation:
dis=30km
time=5/12hr
speed =(dis÷time)
30÷5/12
30×12/5=72km/h
sp=72km/h
time=21/4hr
dis= sp×time
72×9/4=162km
