If a line has a slope of 2/5 a line perpendicular to this line would have a slope of what?

2

-5

-5/2

5/2

-5/2.

Step-by-step explanation:

The slope of the perpendicular line  = -1 / slope of the original line

= -1 / 2/5

= -5/2.

a is the correct

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
