Answer:

1/12

Step-by-step explanation:

This is the answer because:

1) 1/6^2 = 1/36

2) 1/36 x 3 = 3/36 = 1/12 ↔ 3 ÷ 3 = 1 & 36 ÷ 3 = 12 = 1/12

Therefore, the answer is 1/12.

Hope this helps! :D

Write an equation of the line with the given information. m. 4. A(-1.-5)
11Alexandr11 [23.1K]

Answer:

An equation of the line with the given information with

m = 4 and point A(-1, -5) is:

  • y=4x-1

Step-by-step explanation:

As the equation of a line in point-slope form is given by:

y-y_1=m\left(y-x_1\right)

where m is the slope.

Given:

  • the slope m = 4
  • the point A(-1, -5)

Substituting the values in the equation of a line in point-slope form

y-y_1=m\left(x-x_1\right)

y\:-\:\left(-5\right)\:=\:4\:\left(x\:-\:\left(-1\right)\right)

y+5=4\left(x+1\right)

subtract 5 from both the sides

y+5-5=4\left(x+1\right)-5

y=4x-1

Therefore, an equation of the line with the given information

with m = 4 and point A(-1, -5) is:

  • y=4x-1
