stira [4]

Answer:

54 = 6b

Step-by-step explanation:

Sandra rode her bike 54 miles in one day.

She rode 6 times the number of miles Caleb rode his bike.

Let Caleb rode b miles. It means,

54 = 6b

We can also find b as follows :

b = (54/6)

b = 9 miles

Mrac [35]

Answer:

$y=$ $-\frac{5}{6}x - 1$ is the answer

Step-by-step explanation:

Equation of the line: y = 6/5x + 1

= 5y = 6x + 5

= 6x - 5y + 5

Equation of the perpendicular line: bx - ay + k = 0

= -5x -6y + k = 0

Equation passes through (6,-6),

-5(6) -6(-6) + k = 0

-30 + 36 + k = 0

6 + k = 0

k = -6

Substituting,

-5x -6y + k = 0

-5x -6y -6 = 0

-6y = 5x + 6

$y=$ $-\frac{5}{6}x - 1$ (Slope-Intercept form)
