Term Definition
slope-intercept form y = mx + b
standard form Ax + By = C
point-slope form y - y₁ = m(x - x₁)
slope rise over run (also known as m)
direct variation y = kx
constant of variation what the k is in the equation y = kx
x-intercept point where the line crosses the x-axis
y-intercept point where a line crosses the y-axis (also known as b)
vertical line appears in the form x = a where a is any number
horizontal line appears in the form y = a where a is any number
rate of change another name for slope, usually in reference to speed
parallel lines lines that have the same slope
perpendicular lines the slopes of these lines are negative reciprocals of each other (ie. m and -1/m)
-1 the product of the slopes of two perpendicular lines
slope (y₂ - y₁)/(x₂ - x₁)
