Answer:
C. $25
Step-by-step explanation:
We will find,
The slope of the function using .
Taking the points (1,40) and (2,55).
Slope =
i.e. Slope =
i.e. Slope = 15
Substituting the slope and point (1,40) in the equation ,
We have,
i.e.
i.e. b= 25
Thus, the equation of the linear function is .
<em>This linear function represents the cost of the comic book since Lucy purchased it, where x= years.</em>
So, the initial value of the comic book is when x= 0.
So, i.e. y= 25
Hence, the cost of the book when Lucy purchased it was $25.
Answer:
Point lies on
axis and point
lies quadrant III.
Step-by-step explanation:
A coordinate plane is a plane that is divided into four quadrants by the coordinate axes.
Here, coordinate axes are axis and
axis.
Let's first mark the points in the coordinate plane.
See the attached figure.
From the figure, it can be observed that point lies on
axis and point
lies quadrant III.
