5 0

Answer:

6/5

Step-by-step explanation:

We can find the slope given two points by

m = (y2-y1)/(x2-x1)

    = (1 - -5)/(7-2)

     = (1+5)/(7-2)

      =6/5

Write an equation of the line that passes through (-1,7) and is perpendicular to the line y=-1/8x -1
kirill115 [55]

Answer:

y = 8x + 15

Step-by-step explanation:

Step 1: Find slope of perpendicular line

<em>Take the negative reciprocal of the 1st equation</em>

m = 8

y = 8x + b

Step 2: Find <em>b</em>

7 = 8(-1) + b

7 = -8 + b

b = 15

Step 3: Rewrite perpendicular equation

y = 8x + 15
