Answer:
(-7, -10)
Step-by-step explanation:
Substitute x for -7.
Multiply 4 by -7.
Add 28 on both sides.
Divide -4 on both sides.

Answer:
3
Step-by-step explanation:
We have been given graph of a function. We are asked to find the amplitude of our given function.
We know that the Amplitude is the height from the center line to the peak of the function.
We can see that mid-line of our given function is . The amplitude of our given function will be maximum height of our function from mid-line.
We can see that the height of function from mid-line is 3 units, therefore, the amplitude of our given function is 3.

Given:
Angled formed by ray BA and ray BC is 90 degrees.
To find:
The equation of line that bisects the angle formed by ray BA and ray BC.
Solution:
If a line bisects the angle formed by ray BA and ray BC, then it must be passes through point B and makes angles of 45 degrees with ray BA and ray BC.
It is possible if the line passes though point B(-1,3) and other point (-2,4).
Equation of line is
Add 3 on both sides.
Therefore, the required equation of line is .
