Answer: y−3=−3y−43
Step 1: Add 3y to both sides.
y−3+3y=−3y−43+3y
4y−3=−43
Step 2: Add 3 to both sides.
4y−3+3=−43+3
4y=−40
Step 3: Divide both sides by 4.
4y

Answer:
undefined
The problem:
Find the slope for the line going through (3,4) and (3,-4).
Step-by-step explanation:
Line up points vertically and subtract.
Then put 2nd difference over 1st.
( 3 , 4)
-(3 , -4)
------------
0 8
So the slope would have been 8/0 but this is undefined.
So the slope is undefined.
Also notice the x's are the same and the y's are difference so this is a vertical line. There is only rise in a vertical line and no run. Recall, slope is rise/run. You cannot divide by 0 so this is why we say the slope is undefined when the x's are always the same no matter the y.
The answer is b because each x value has one y value.
Answer: y= -3/8
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation
