slope
the steepness of a line
slope intercept form
y=mx+b
point slope form
ysub2-ysub1=m(xsub2-xsub1)
standard form
Ax+By=C
slope formula
m= change in y/change in x = (ysub2)-(ysub1) / (xsub2)-(xsub1)
linear equation
equation of a line
x-intercept
the x coordinate of the point where the line crosses the x-axis (the y coordinate is 0)
y-intercept
the y coordinate of the point where the line crosses the y-axis (the x coordinate is 0)
negative reciprocal
opposite reciprocals (ex: 4 and -1/4)
translation
the sliding of the graph of an absolute value equation
parallel lines
lines with the same slope and different y-intercepts
perpendicular lines
lines that intersect to for a right angle (their slopes are opposite reciprocals)
