I'm assuming you are finding the equation of the line of Line J
Slope-intercept form: y = mx + b
[m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis]
For lines to be perpendicular, the slopes have to be negative reciprocals of each other. (basically changing the sign (+/-) and flipping the fraction/switching the numerator and the denominator)
For example:
slope = 2 or 
Perpendicular line's slope = 
[changed sign from + to -, and flipped the fraction]
slope = 
Perpendicular line's slope = 
[changed sign from - to +, and flipped the fraction]
Since you know the slope is 3, the perpendicular line's slope is 
. Plug this into the equation
y = mx + b
To find b, plug in the point (3, 8)
8 = -1 + b Add 1 on both sides to get "b" by itself
8 + 1 = -1 + 1 + b
9 = b
20/29
16/34
40/41
21/20
30/40
21/29
35 is the correct answer choice
This is a quadratic in the form of ax squared +bx +c
So
a = 3
b = -5
c = 2
Hope this helps!
Let's add up all of the other sports except baseball (which we don't know)
1/3 + 1/8 + 5/12 Common denominator is 24 so let change them to 24ths
8/24 + 3/24 + 10/24 = 21/24 Since all the sport put together can be represented by the number 1, we will do 1 - 21/24
Instead of 1, I will use 24/24 (which means 1)
24/24 - 21/24 = 3/24 or 1/8 reduced. 1/8 of the student named baseball as their favorite sport.
