Parallel / Perpendicular Practice Convert all equations to slope intercept form. Show work.
Compare slopes. Determine if I or || or Neither
1. y = 3x + 1
y = x + 1
2. y=5x - 3
10x - 2y = 7
3. - 2x - 4y = -8
-2x + 4y = -8
4. 2y - x = 2
y = -2x + 4
5. 4y = 3x + 12
-3x+4y=2
6. 8x - 4y = 16
5y - 10=3
8. 2x - 5y=-3
5x + 27 = 6
7. 2x+6y=-3
12y = 4x + 20

What situation is an example of an observational study

Which exponential function has an initial value of 2? f(x) = 2(3x) f(x) = 3(2x)
