Understanding Parallel Lines and Y-Intercepts

What is the significance of two lines being parallel in terms of their slopes?

• Their slopes are negative reciprocals.

• One line has a slope of zero.

• They have the same slope.

• They have different slopes.

What is the first step in rearranging the given line equation to find its slope?

• Convert it to point-slope form.

• Convert it to slope-intercept form.

• Multiply all terms by a constant.

• Add a constant to both sides.

Which formula is used to derive the equation of a line given a point and a slope?

• Standard form equation

• Slope-intercept formula

• Point-slope formula

• Quadratic formula

How do you find the y-intercept of a line from its equation?

• Use the quadratic formula.

• Set x to zero and solve for y.

• Find the slope and multiply by x.

• Set y to zero and solve for x.
