Point form (0,1) and equation form is x = 0 y = 1
X + 2y = 10 becomes x + 2(2x-4) = 10. Thus, x + 4x - 8 = 10, and 5x = 18.
Answer:
Part a) The grade is 3.2%
Part b) This grade meet the rapid-transit rail standard
Step-by-step explanation:
we know that
The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)
In this problem we have


so

convert to percentage

Round to the nearest tenth of a percent


therefore
This grade meet the rapid-transit rail standard
