90 degree rotation clockwise : (a,b) --> (b,-a)
so... (24,-15) --> (-15,-24) is a 90 degree clockwise rotation
Answer:

Step-by-step explanation:
The equation of a straight line can be written as
.
With the pair of coordinates (coordinates are written in the form
) , the following can be written:


To solve for a variable, we can use elimination:
(subtract the second equation from the first)
(
is eliminated)


To solve for the other variable, we can use substitution:



is the linear equation for the line that passes through the points
and 
Answer:
Zero
Step-by-step explanation:
The solutions to a system of equations are where the lines intersect. These lines have the same slope meaning they are parallel. Parallel lines never intersect, therefore there are zero solutions.
