Line L is perpendicular to a line with slope -5 and passes through (2, -2). Find an equation of line L and write the answer in t

irina [24]

Answer:

y=1x +8

Step-by-step explanation:

y-y1 = m(x-x1)

y+2 = -5(x-2)

y+2 = -5x + 10

y = -5x +8

Now to find line L we have to change the slope because it is perpendicular

y= 1x +8 (The slope is one fifth, but idk

5. to put it, I'm sorry)
