Answer:
Answer is y = 2x - 3
Step-by-step explanation:
• Equation of parallel lines have the same slope. So first two equations are okay.
• For point (1, -1):
• Equation is y = 2x - 3
Answer:
No real solutions;
Step-by-step explanation:
The easiest method to solve an algebraic equation is to use inverse operations. This applies to the given equation;
- Take the square root of both sides
==================================================================
As one can see, the right side is a negative number. However, one cannot take the square root of a negative number and get a real result. Therefore, one must use imaginary numbers. Remember, the imaginary unit () represents (
).
==================================================================
- Add (3) to undo the (-3)
- Divide by (2) to remove the coefficient of (2x)
