Answer:
A
Step-by-step explanation:
You can subtract normally when the square roots are the same( like in your problem) but the squares stay they same and the numbers on the outside change.
me
1.22222
Use the equation y2-y1/x2-x1=m to find the slope.
Now, just insert your known values.
15-4/4--5=m
11/9=m
1.22222 is the slope.
Hope this helps!
