-7x + 63y = 9?"
Slope-intercept form is y = mx + b
m is the slope
b is the y-intercept
-7x + 63y = 9
63y = 7x + 9 {added 7x to both sides}
y = (1/9)x + 1/7 {divided both sides by 63}
slope = 1/9
Perpendicular lines have slopes which are negative reciprocals.
If the slope of this line is 1/9,
the perpendicular line would have a slope of -9.
You can put this solution on YOUR website! -7x + 63y = 9
Solve for y
63y = 7x + 9
y = (1/9)x + 1/7
Slope m = 1/9
--------------
The slope of lines perpendicular is the negative reciprocal = -9
