Answer:

The perpendicular slope would be -1/5.

Step-by-step explanation:

This is because we can locate the slope of the original line as 5 (the number just outside of the x-coordinate parenthesis.

Then we know that perpendicular lines have opposite and reciprocal slopes. So we take the 5 and change the sign (-5), then we flip it (-1/5).

What is the answer to this hard question -5k - 19 = 5 -13k

Gwar [14]

You are trying to solve for k (get k by itself)

-5k - 19 = 5 - 13k Add 19 on both sides

-5k - 19 + 19 = 5 - 13k + 19

-5k = 24 - 13k Add 13k on both sides

-5k + 13k = 24 - 13k + 13k

8k = 24 Divide 8 on both sides

k = 3
