The answer is A, gonna let you know Desmos is your best friend. I use it all the time.

1)

The equation is in form y=mx+b

m is the slope and b is the y-intercept

Slope: -6 and y-intercept: 2

2)

The equation is in form y=mx+b

m is the slope and b is the y-intercept

Slope: 1 and y intercept: -3

3) 

C = 14d + 3

4) 

8x + 6y = 12
6y = -8x + 12
y = -4/3 + 2

5)

First change the equation to y=mx+b form.

4x + 6y = 12
6y = -4x + 12
y = -2/3x + 2

Slope: -2/3

Hope that helps :)
