Answer:
Step-by-step explanation:
so whats your question?
Let

If M is the midpoint, the x and y coordinates of M are the average of the x and y coordinates of P and Q:

We can solve this expression for the coordinates of Q:


Plug in the values for the coordinates of M and P to get


Answer:
y=3x-4
Step-by-step explanation:
Slope intercept form is :
y=mx+b
where m is the slope, and b is the y intercept.
We are given the slope, it is 3. we are also given the y intercept, it is (0,-4). For this form, the 0 in (0,-4) is ignored, and we consider the y intercept to be -4.
So, m is 3, and b is -4. Substitute the values into the equation
y=3x+ -4
y=3x-4
So, the equation in slope intercept form is
y=3x-4
For number 12 the answer is 15.36
