Answer:

y=-2x-10

Explanation:

Let us start with a general slope-intercept equation, y=mx+b, where m represents the slope, b represents the y-intercept, and the y and x represents the coordinates the line passes through.

Therefore, the slope of our line


y=(1)/(2)x-5

is 0.5

We also know that the perpendicular slope is simply the negative reciprocal of the current slope. We know have:


-(2)/(1) =\\-2

Now, let us find the y intercept. We can plug in the x and y values using the given coordinate (–6,2).


y=-2x+b\\2=-2*(-6)+b\\2=12+b\\b=-10

Now, we can write our equation:


y=-2x-10

I hope this helps! Let me know if you have any questions :)

Answer: y=-2x-10

Work:
m=(1/2)
m perpendicular= -2
2=-2(-6)+b
b=-10

Explanation: the standard form of the equation of a line is y=mx+b, find the y-int and perpendicular slope.
