Answer to Problem 47PPS
Explanation of Solution
Given information :
Line containing (-4, 9) and (4, 3) is parallel to the line containing (-8, 1) and (4, y )
We know that the slope of a line is given by the formula,
We know that when the lines are parallel then their slope are equal.
Hence both lines have same slope. Therefore we get,
Now points on the line are (-8, 1) and
