Answer:
5
Step-by-step explanation:
When squaring the number 5 (i.e ) the answer is 25.
is the same thing as 5 times 5. Basically with the square root, you are going backwards, so you are therefore finding the base of it all.
Step 1: Find the slope:
This gives you , but we need to find b.
To find b, substitute in one (x,y) pair and it doesn't matter which one. I'll go with (4,-2):
Now take that b-value and plug in into the slope-intercept form:
It's always a good idea to toss in the other x-value from the other point, to make sure it checks out.
