Will mark brainliest The temperature in degrees Celsius (C) can be converted to
degrees Fahrenheit (F) using the formula F(C)=2C+k,

where k is a constant. Find k, if to C= -40°C corresponds
F=-40°F.

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

current in the circuit at time t is /, then the power delivered to the resistor is
