Passing through (-2, 8) and PERPENDICULAR to y = 2x + 5
tangare [24]

Answer:

y=\frac{-1}{2} x+7

Step-by-step explanation:

The slope of a perpendicular line will always be the NEGATIVE RECIPROCAL of the slope of the original line.

y=2x+5

Because this equation is organized in slope-intercept form, y=mx+b, we can identify the slope of the original line is 2. The negative reciprocal of 2 is \frac{-1}{2}. Therefore, the slope of the perpendicular line is \frac{-1}{2}. So far, our equation looks like this:

y=\frac{-1}{2}x+b

Now, we must solve for b, the y-intercept of this line. To do that, we can plug in the given point (-2,8) and solve for b:

y=\frac{-1}{2}x+b\\8=\frac{-1}{2}(-2)+b\\8=\frac{2}{2} +b\\8=1+b

Subtract both sides by 1 to isolate b

8-1=1+b-1\\7=b

Therefore, the y-intercept of this line is 7.

After plugging both the slope and the y-intercept into y=mx+b, we get:

y=\frac{-1}{2} x+7

I hope this helps!
