Find The Equation of the Line Parallel to Another Line

Find the equation of a line that is parallel to a given line and passes through a specified point. Generate random problems, see detailed step-by-step solutions, and visualize both lines on a graph.

📐 Parallel Line Through a Point

Find line parallel to \( a_1x + b_1y = c_1 \) through point \( (x_0, y_0) \)

Line: \( 2x - y = 3 \), Point: \( (1, 2) \)
Find the equation of the line parallel to the given line through the point.

📖 Step-by-Step Solution

STEP 1: Write the given line in slope-intercept form (y = mx + b)
—
STEP 2: Identify the slope m₁ of the given line
—
STEP 3: Parallel lines have equal slopes (m₂ = m₁)
—
STEP 4: Write the equation in point-slope form
—
STEP 5: Convert to slope-intercept form
