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

Options:

Correct Answer: y = 3x - 1

Exam Year: 2020

Solution:

Parallel lines have the same slope. Using point-slope form: y - 2 = 3(x - 1) gives y = 3x - 1.

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

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

Step 1: Identify the slope of the given line y = 3x + 4. 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 (1, 2) and m is 3.
Step 4: Substitute the values into the point-slope form: y - 2 = 3(x - 1).
Step 5: Simplify the equation. Distribute 3: y - 2 = 3x - 3.
Step 6: Add 2 to both sides to solve for y: y = 3x - 1.
