In Exercises 21 and 22, consider the three given lines. Line a: through the point (2,0) with a y-intercept of (0, 1)
Line b: through the point (2,0) with a y-intercept of (0,5)
Line c: through the point (2,0) with a y-intercept of (0,3)

21. Which line is most steep?
22. Which line is least steep?

21. Line b.

22. Line a.

Step-by-step explanation:

Line b is the most steep because it goes up 5, the rest goes up only 1 and 3

Line a is the least steep because it only goes up 1, while the rest go up more

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
