A line has a slope of 1 and y-intercept of - 4 what is it's equation in slope - intercept form

I have no idea, I just need to answer one question then I have one to ask

y = x - 4

Step-by-step explanation:

y = mx + b is slope - intercept form.

b is your y-intercept while m is your given slope. since your slope is 1, you don't have to write out 1x because x is already known as 1. - 4 is your y - intercept or b so it would be minus 4 since it's a negative.
