Answer:
Step-by-step explanation:
slope=(-1-0)/(6-3)=-1/3
reqd. eq. of line is
y-0=-1/3(x-3)
3y=-x+3
x+3y=3
Answer:
y = - 3
Step-by-step explanation:
Given
= 
( cross- multiply )
9(y + 2) = 3y ← distribute left side
9y + 18 = 3y ( subtract 3y from both sides )
6y + 18 = 0 ( subtract 18 from both sides )
6y = - 18 ( divide both sides by 6 )
y = - 3
To find Ken's speed divide total distance by total time:
174 miles / 3 hours = 58 miles per hour.
In the equation for Brenda, the 57 is the miles per hour because you would multiply that by x ( hours) to get total miles (y).
Ken had the faster driving speed.
