Perpendicular lines meet each other always at an angle of 90 while intersecting lines may or may not have an angle of 90.
Their opposite angles(made by intersecting lines) are always same.
And even, we can say every perpendicular lines as intersecting but can't say that every intersecting line is perpendicular.
The answers are:
(-1,1) and (-6,-1)
(1,0) and (6,2)
(3,0) and (8,2)
So for this our goal is to isolate t since its the total price. All you have to do is add yz on both sides of the equation, and your answer should be
I can not see the picture?
There is no rate of change of Function 1. It's slope(rate of change) is zero.
Function 2 has a slope of 2.
