Question: Find the equation of the line parallel to y = 5x - 3 that passes through the point (2, 1).

Options:

Correct Answer: y = 5x - 9

Solution:

Since the slope is the same (5), using point-slope form: y - 1 = 5(x - 2) gives y = 5x - 9.

Find the equation of the line parallel to y = 5x - 3 that passes through the point (2, 1).

Find the equation of the line parallel to y = 5x - 3 that passes through the point (2, 1).

Step 1: Identify the slope of the given line y = 5x - 3. The slope (m) is 5.
Step 2: Since we need a line parallel to this one, it will have the same slope, which is also 5.
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).
Step 4: Substitute the values into the point-slope form: y - 1 = 5(x - 2).
Step 5: Simplify the equation. Start by distributing the 5: y - 1 = 5x - 10.
Step 6: Add 1 to both sides to solve for y: y = 5x - 10 + 1.
Step 7: Combine like terms: y = 5x - 9.
Step 8: The final equation of the line parallel to y = 5x - 3 that passes through (2, 1) is y = 5x - 9.
