We have to determine the equation of the line passing through the point (2,-5) and parallel to the line
When two lines are parallel, then the slopes of the two lines are equal.
Equation of line with point and slope 'm' is given by:
Since, we have to determine the equation of a line with point (2,-5).
So, the equation of the line is :
Since, the line is parallel to the line
So,
So, slope of the line 'm' is .
Therefore, the equation of the line is:
Therefore, is the required equation of the line.
Option D. 96 is the correct answer.
Explanation:
Let the higher grade be = x
Let the lower grade be = y
As given, The difference of the two grades is 16
or
.... (1)
The sum of one-eighth of the higher grade and one-half of the lower grade is 52.
... (2)
Putting the value of x=16+y in equation (2)
As x=16+y
x=16+80 = 96
Hence, higher grade is 96.
