Lines a and b are perpendicular. If the slope of line a is 3, what is the slope of
line b?

-1/3

Step-by-step explanation:

Perpendicular lines have slopes that multiply to -1

a*b = -1

3 * b = -1

b = -1/3

The slope of line b is -1/3

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)

a) 32pie square meters
