A. Determine whether each is a linear function or not. Check Yes if it is a linear function and No if it is not. Write the degree of the function. For linear functions, identify its slope m and y-intercept b.
Degree. Yes. No. m. b.
1. y = 3x + 4
2. y = 5x-2
3. y = x² + 5x + 4
4. y = -7x + 1
5. y = -2x - 3
6. y = x² + x - 12
7. y = -x + 5
8. y = 5
9. y = x² - 2x - 15 y =
10. y = 4x
