Question: What is the equation of the line parallel to y = 3x - 4 that passes through the point (2, 1)? (2020)

Options:

Correct Answer: y = 3x - 1

Exam Year: 2020

Solution:

Since parallel lines have the same slope, the equation is y - 1 = 3(x - 2) which simplifies to y = 3x - 5.

What is the equation of the line parallel to y = 3x - 4 that passes through the point (2, 1)? (2020)

Step 1: Identify the slope of the given line. The equation is y = 3x - 4, so the slope (m) is 3.
Step 2: Since parallel lines have the same slope, the slope of the new line will also be 3.
Step 3: Use the point-slope form of the equation of a line, which is y - y1 = m(x - x1). Here, (x1, y1) is the point (2, 1) and m is 3.
Step 4: Substitute the values into the point-slope form: y - 1 = 3(x - 2).
Step 5: Simplify the equation. Distribute 3: y - 1 = 3x - 6.
Step 6: Add 1 to both sides to isolate y: y = 3x - 5.
