1. How do I work out the gradient of 2x+3-2=0?
2. I think that what you need to do it simplify it to get:
2x+1=0
Then, you can subtract both sides by 1 to get:
2x=-1
Finally, both sides can be divided by 2:
x= -0.5

This is merely the suggested steps to be followed in the event that y is not provided in the equation. However, it may not be correct. I think @razzer has a much better answer.

I hope that helps.

Have you typed the question out correctly? After simplifying, you will notice that the equation you stated is just the equation of a vertical line (x = - 0.5) making it have infinite gradient.
There must be a 'y' part missing in your equation.

Thanks for addressing this. I didn't make my answer clear enough. It was also just a suggestion so I think your answer is correct.
6. It is undefined because it's a vertical line and it can be seen when you rearrange the equation you get X=-0.5

However, there must be a mistake in your question because there must be a y component?

thank you very much, yes I think that there must be a mistake on the sheet
