How do you add and subtract square roots?

You can subtract square roots with the same radicand-- which is the first and last terms. Only the first and last square root have the same radicand, so you can add these two terms. Remember-- the same rule applies to subtracting square roots-- the radicand must be the same.

if you graph these points, you'll see that the line is horizontal, so the slope is zero. It will cross the y axis (y intercept) at y=1.

Step-by-step explanation:

Slope = y2-y1/x2-x1, so in this example:

m = 1-1/it doesn't matter because the answer will be zero!!

Now for slope intercept form:

y = mx + b

y = 0x + b; take one of your points and plug it in:

1= 0(2)+ b

1=0 + b

1=b

So your equation is:

y= 0(x) + 1

y=1
