m = - 1/7
y - 8 = (- 1/7).(x + 2)
y = (- 1/7).x - 2/7 + 56/7
y = (- 1/7).x + 54/7

First, confirm the perpendicular slope of the hot line. you have already got the slope of 7, so it is perpendicular is in basic terms the unfavorable reciprocal that's -a million/7. So, m = -a million/7 Now, write the equation using the slope intercept variety: y-y1 = m(x-x1) by potential of plugging in the hot slope and the element you get y - 8 = - a million/7 (x - 2) distribute to get y - 8 = -a million/7x + 2/7 pass the 8 to the different part by potential of including it on the two sides y = -a million/7 x + (2/7 + 8) remedy it to get the hot line equation that's: y = - a million/7 x + 8 2/7

The slope of the perpendicular line is the negative reciprocal of the slope of the given line.
m = -1/7
Using the point slope formula for the line we have:
y - 8 = (-1/7)(x + 2)
y = (-1/7)x - 2/7 + 8
y = -x/7 + 54/7

the line perpendicular has the slope of the negative reciprocal, so the equation is
y= -1/7x+3
