You divide 5.625 by 125 and that's x and for y you multiply 420 to 1,875
The rate of change is the slope. You're finding the average between two points, so find the slope between them using the slope formula. It's 20.
Step-by-step explanation:
m is the slope.
plug in the numbers, and you get
True. If the ends of a line are contained in the same plane, then the line has to be in the same plane.
Expand and collect like terms:
10x > 5(x-4)
10x > 5x-20
5x > -20
x > -4, so the answer is B
