linear equation
equation in which the power of the variable (x) is 1. When graphed on the coordinate plane these equations are a straight line.

slope
slope- intercept form
form of linear equation. (y=mx+b)
form of linear equation (y=mx+b)
slope-intercept form
y-intercept
the point where a line crosses the y-axis on the coordinate plane
the point where a line crosses the y-axis on the coordinate plane
y-intercept
form of linear equation
(y-y1) = m(x-x1)
point-slope form

perpendicular lines
lines that meet or intersect at right angles. Their slopes are negative reciprocals of each other
