Determine whether each is a linear function or not. Write the degree of the function. For linear function, identify its slope and y intercept :)

1. f(x)= 2(x-3)
2. f(x)= (x+5)
3. f(x)= 3x
4. f(x)= x-4

THANKS :)

anonymous · Answer

they're all linear function and have the first degree (x^1)

the slope is what is in front of x:
1. 2x (you have to multiply parentheses), so 2
2. x, so 1
3. 3x, so 3
4. x, so 1

the y-intercept is the numerical with no attached variable
1. -6 (you have to multiply parentheses)
2. 5
3. 0 (there is no numerical )
4. -4
