Slope form

Slope-Intercept Form

A way to express the equation of a straight line in the format y = mx + b.

m (in slope-intercept form)

Represents the slope of the line, indicating how steep the line is.

b (in slope-intercept form)

Represents the y-intercept, the point where the line crosses the y-axis.

Usage of Slope-Intercept Form

Commonly used in algebra to easily graph linear equations and analyze their relationships.

Parallel Lines

Straight lines that have the same slope but different y-intercepts.

Graphical Representation of Parallel Lines

Parallel lines never intersect and maintain a constant distance apart.

Perpendicular Lines

Straight lines that intersect at a right angle (90 degrees).

Slope point form

y - y1 = m(x - x1)

What are the two formulas you can use to find the slope of perpendicular lines or parallel lines

Y=mx+b or y-y=m(x-x)
