Please help and explain how you answered it

y =  -5/7x -32/7

Step-by-step explanation:

To find the perpendicular line, it is the opposite opposite slope. this means that you change if it was positive or negative, and you flip the numerator and the denominator. so, because this slope is positive, you turn it to be negative. then you would switch the numerator and denominator, making the slope of the other line -5/7 (m). then you use y=mx + b to find the equation of the other line. you use (2,-6) and fill in the values to find be, so you would do

-6 = (-5/7)(2) + b so then you solve

-6 = (-10/7) + b  

-32/7 = b

and then you fill in the y=mx +b to get y =  -5/7x -32/7
