Answer:

C


Step-by-step explanation:

General Form of an equation of a line is given by:  y=mx+b

Where,

m is the slope, and

b is the y-intercept (point where line cuts the y-axis)

Also, parallel lines have equal slopes.


Equation of first plane is given as  d=3.67t+4.81

Comparing this with general form of a line, we see that 3.67 is the slope and 4.81 is the y-intercept.

<em>The </em><em>second plane </em><em>is going </em><em>parallel</em><em> to this. So slope should be same. Hence </em><em>second plane has slope of 3.67. </em><em>We can write:</em>

<em>d=3.67t+c</em>


<u>To find the equation of second plane</u>, we need to solve for c. Also, a point given for second plane is (t=0, d=2.14) , substituting these values into the equation we got, we get the value of c:

2.14=3.67(0)+c\\2.14=0+c\\c=2.14


We already know m and now we know c, so we can write final equation as:

d=3.67t+2.14

Answer choice C is right.
