The slope is 1, to find what the y-intercept is, find a random point on the graph and plug it in. I’ll use (5,0) for example. Of those ordered pairs, the first number(5) is the x, and the second number(0), is the y. So fill those in on the equation y = 1x + b.
0 = 1(5) + b
0 = 5 + b
Now to make the b be by itself subtract 5 from both sides.
-5 = b
Final answer:
y = 1x - 5
