Answer:
C
Step-by-step explanation:
General Form of an equation of a line is given by:
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
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></em>
<u>To find the equation of second plane</u>, we need to solve for c. Also, a point given for second plane is , substituting these values into the equation we got, we get the value of c:
We already know m and now we know c, so we can write final equation as:
Answer choice C is right.
