Answer:
Therefore the equation of the line has a slope 2 and passes through ( 10 , 17 ) is
2x - y = 3
Step-by-step explanation:
Given:
Slope = 2 = m ( say )
Let,
point A( x₁ , y₁) ≡ ( 10 , 17 )
To Find:
Equation of Line AB =?
Solution:
Equation of a line passing through a points A( x₁ , y₁) and having slope m is given by the formula,

Substituting the given values in a above equation we get

Therefore the equation of the line has a slope 2 and passes through ( 10 , 17 ) is
2x - y = 3
Answer:
It took Pedro <em>3.81 hours</em> to reach the lake.
Step-by-step explanation:
Time taken by Mike to hike a lake = 4.5 hours
Average rate of Mike while hiking the lake = 
Formula for distance can be seen as:

Distance traveled by Mike = 
Rate of Pedro while hiking the same distance = 
Given that, Pedro also travels the same distance.
And we have to find the Time.


It took Pedro <em>3.81 hours</em> to reach the lake.
