a./ Gradient 2, intercept (0,10)

I know that it is against the rules, but could you at least walk me through on this one question? There are about 30 of them and I don't get them at all... Please, pretty, pretty please?

Thanks...

Start with the fundamental linear equation y = mx + b.

You've been given the slope ('gradient') m = 2; you also have the y-intercept b = 10. Just pop those in...

y = 2x + 10

... and you can mark that one "done".
