1. y=2.5x
2. 4x+3y=12
3. x=4
4. 6y=2x-18

The first step to finding slope and Y-intercept is to put these equations in standard form. Once the equation is in standard form, you can easily find slope and Y-intercept.
Standard form is: Y=MX+B
where M is the slope and B is the Y-intercept
For example for your first equation you have: Y=2.5x
This equation is already in standard form so we can derive from the formula that 2.5 is the slope. Since there is no B given you know that the Y-intercept is 0.
This should be enough assistance to get you started with the other three. Good Luck!
