# Math

slope y-intercept y=mx+b
standard form Ax+By+C=0
slope equation y2-y1/x2-x1 or for a graph rise/run
fixed number y-intercept
variable number/constant multiple/ constant of variation slope
m= slope
b= y-intercept
horizontal lines slope is zero, slope in equation is y=0x+b, y=b is the equation
vertical lines slope doesn't exist=undefined, can't use slope y-intercept for vertical lines, written in the form x=a where a is the x-intercept
direct variation passes through the origin (0,0) y=mx
partial variation doesn't pass through the origin (0,0) y=mx+b
linear points form a straight line, first differences are constant
non-linear points don't form a straight line, first differences aren't constant
linear system a set of two or more linear equations that are considered simultaneously
point of intersection the point where two (or more) lines cross
two parallel lines never cross, no common points, no solution
two non-parallel lines intersect at one point, one solution
two identical lines equation different but same line, infinite number of solutions
parallel lines lines which run in the same direction and never cross
perpendicular lines lines which intersect at right angles (90o)
how to know if two equations are parallel they have equal slopes
how to know if two equations are parallel the slopes are negative reciprocals
x-intercept the value of x where the line crosses the x-axis (y=0)
y-intercept the value of y where the line crosses the y-axis (x=0)
