I’m almost positive it’s C
Answer:
a) -1
Step-by-step explanation:
Slope is also known as the gradient
1. assign a value to x and solve for y:
when x = 2, y = 2
when x = 4, y = 0
2. Next, use the equation of a straight line to find the gradient
y = mx + c
y is the y-coordinate, m is the gradient, x is the x-coordinate, c is the point where the line crosses the y-axis, which is found by equating y to 0 and solving for x
so y = mx + c becomes 2 = m*2 + 4, which then becomes 2 = 2m + 4
2m = -2 (take 4 away from 2)
<u>m = -1 </u>
Answer:

The population of city is 10 millions in year 2015 that is 5 years after 2010.
Step-by-step explanation:
We are given the following information in the question:
The population of a city, P, in millions, is a function of t.

where P is the population of city in millions and t is the number of years after 2010.
We have to interpret the meaning o the statement f(5) = 10.

Interpretation:
Comparing the relation we get,
It means that the population of city is 10 millions in year 2015 that is 5 years after 2010.
