Answer:

Step-by-step explanation:
In order to find the slope of a line you must find where the points intersect, use the formula for slope, substitute values, and simplify if needed.
In this case we were already given the points for slope:


Slope formula:

Now substitute:

Solve using KCC: (Keep, Change, Change)


=
Because the slope isn't a negative you do not need to simplify the answer.

Answer:

Step-by-step explanation:
where A is angle and a is side opposite of angle
cross-multiply



The y-intercept of the function is at y = -3 so the options that don’t include it are off the table. The only possible answer is option C. Option A doesn’t work because plugging in positive values would give negative numbers within the square root which isn’t defined in the real numbers.
