Answer:
The equation of line M in slope intercept form is 
The equation of line M in standard form is 
Step-by-step explanation:
step 1
Find the slope of line M
The formula to calculate the slope between two points is equal to
we have the points
(2,4) and (0,1)
substitute
step 2
Find the equation of the line M in point slope form
we have
substitute
----> equation in point slope form
step 3
Find the equation of line M in slope intercept form
Isolate the variable y in the equation of the line in point slope form
Adds 1 both sides
step 4
Find the equation of the line M in standard form
where
A is a positive integer
B and C are integers
we have
Multiply by 2 both sides
---> equation in standard form
Karen is moving at 81.2 miles per hour while Melinda is moving at 71.2 miles per hour.
<h3>Equation for
speed</h3>
Speed is the ratio of total distance travelled to total time taken. It is given by:
Speed = distance / time
Let a represent Karen speed and b represent Melinda speed, hence:
a = b + 10
a - b = 10 (1)
Also:
a = d₁ / 1
d₁ = a
b = d₂/ 1 hour
d₂ = b
Since they are 108 miles apart, using Pythagoras:
108² = d₁² + d₂²
a² + b² = 11664
(b + 10)² + b² = 11664
b = 71.2 mph, a = 81.2 mph
Karen is moving at 81.2 miles per hour while Melinda is moving at 71.2 miles per hour.
