Each letter a and b represent a question math

2x - 6y = 12

6y = 2x - 12

  y = 1/3 x - 2

a) 4 points:

x = 0, y = -2 > (0, -2)

x = 3 ; y = 1/3 (3) - 2 = 1 - 2 = -1  > (3,-1)

x = - 3; y = 1/3 (-3) - 2 = -1 - 2 = -3 >(-3,-3)

x = 6; y = 1/3(6) - 2 = 2 - 2 = 0 >(6,0)

4 points: (0, -2), (6,0), (3,-1) and (-3,-3)

b)

Use those 4 points from a to graph the b question

answer: x

step-by-step explanation:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
