Understanding Parallel Lines and Slope

The video tutorial explains how to find the equation of a line parallel to a given line and passing through a specific point. It starts by identifying the slope of the given line by converting it into slope-intercept form. Then, it uses the point to find the y-intercept of the new line. Finally, it demonstrates graphing both lines to show their parallel nature.

What is the main goal of the problem introduced in the video?

• To find the intersection of two lines

• To find a line parallel to a given line passing through a specific point

• To calculate the area under a curve

• To determine the midpoint of a line segment

What is the y-intercept of the line passing through the point (3, 0) with a slope of 1/2?

• 0

• 2

• 3/2

• -3/2

What is the equation of the line parallel to 2x - 4y = 8 and passing through (3, 0)?
