hello, Just wondering if anyone can help me out with this question my teacher set me, thanks "Find the equation of a line with a gradient of -4 and an x-intercept of 5" hope someone can help...

Thanks, I know the formula, I think I need to know how to find the y-intercept to keep going from here because I know how to do it with both intercepts, if you could help me find out how that would be great
