Note:
Any line that has a zero slope is a horizontal line.
Any line with an undefined slope is a vertical line.
So if the line has undefined slope and passes through (3/2, 2/3)
At that point x = 3/2 = 1.5, and y = 2/3.
The graph would be a line that is vertical, and as such it would an equation:
x = 3/2. This is the vertical line.
x = 3/2
Answer: Mary is 25 David is 20
Step-by-step explanation:
I think it's possible 10?
1. vertical angles, so 2x=74, x=37
2. vertical angles, so 126=x+77, x=126-77=49
3. (6x-21) vertical to 105,
so 6x-21=105
6x=126
x=63
4. 8x vertical to (55+85)
8x=140
x=17.5
