Answer: y= 1/5 x + 8

Explanation:

To get a perpendicular line, take the reciprocal of the original "m" in the equation and reverse the sign.

- 5 becomes +1/5

Then substitute the y and x values from the given coordinate into the new equation and solve for b

y= mx+b

6=1/5 (-10) + b

6 = -2 +b

8 = b rewrite the new equation and substitute 8 for b

y= 1/5 x + 8

The attached screenshot shows the lines and the point.
