First find the slope of A.
Slope=(y2-y1)/(x2-x1)=(4-0)/(0--7)=4/7
For a line to be perpendicular to line A, it must have a slope that is the negative reciprocal of the slope of A. Mathematically:
m1*m2=-1 and in this case the perpendicular line will have a slope of:
4m/7=-1
4m=-7
m=-7/4
So the slope of the line perpendicular to A is -7/4
Answer:
Understanding a concept like the coordinate plane often means putting the abstract terminology and descriptions into a real-world setting. Mathematics describes the real world, but often it isn’t clear how the concepts translate to real life. Coordinate planes range from being abstract representations of other variables to spatial coordinates that are easy to find real-world examples of. To use a coordinate plane in real life, simply choose what type of system you’re going to use and define the directions they go in. However, you need to consider a few more complicated ideas to get the most out of it.
