1. (3,2)....because when finding the slope, we find the the slope of mn and the slope of op are negative reciprocals.
2. y = 5x - 7.....slope here is 5....perpendicular line has a negative reciprocal slope...so the slope has to be -1/5
y= mx + b
slope(m) = -1/5
(-10,3)...x = -10 and y = 3
now we sub and find b, the y int
3 = -1/5(-10) + b
3 = 2 + b
3 - 2= b
1 = b
so ur perpendicular equation is : y = -1/5x + 1
Solve this problem by setting up a proportion to model the number of boys to the total number of students than the class:
80/100=20/x
Now, cross multiply:
80x=2000
Then, divide 2000 by 80 to solve for x:
x=25
25 is the total number students in the class.
Hope this help
