Answer:
c= 3/5(n)+2.5
Step-by-step explanation:
Let
c -----> the cost of some taxi journeys
n ----> the number of miles
we know that
The graph is a line
The equation of a line in slope - intercept form is
c=m(n)+b
where
m is the slope
b is the c-intercept (value of c when the value of n is equal to zero)
Observing the graph we have the points
(0,2.5), (5,5.5)
Find the slope
The formula to calculate the slope between two points is equal to
m= c2-c1/n2-n1
substitute the values
m=5.5-2.5/5-0
m=3/5
we have
b=2.5 -----> because the point (0,2.5) is the c-intercept
substitute in the equation of slope-intercept form
c=3/5(n)+2.5
I hope that gives you your answer please mark me brainliest :)
