Answer: 6u
Step-by-step explanation:
The slope of the line
is
.
The line perpendicular to the above line has slope
Its equation is
. Since this line passes through,
,

Thus the equation of the line in slope intercept form is 
The first one: -7(x) + 4(y) = 24
The second one: 4(x) - 4(y) = 0
4y - 7x = 24 which is reduced to a negative
(-4y + 4x = 0 )
4(x) = 4(y)
-7(y ) + 4(y) = 24
- 3(y) = 24
3(y) = - 24
y-intercept: - 8
x-intercept: -8
The X & Y intercept is: -8, -8
535 points. You could either add 867 to -332 or subtracted 332 from 867. I hope this was helpful.
