Alg 1 EOC RC3 terms
Term | Definition |
---|---|
domain | the possible values for x; the independent variable of a function |
range | the possible values for y; the dependent variable of a function |
perpendicular lines | lines that intersect at right angles; have slopes that are negative reciprocals of one another |
parallel lines | lines that never intersect; have the same slope |
slope-intercept form | y = mx + b |
point-slope form | y - y1 = m(x - x1) |
standard form | Ax + By = C |
system of linear equations | two or more linear equations working together for a common solution; may have no solution, one solution, or infinitely many solutions |
varies directly/direct proportion | when x increases, y increases by the same factor; y = kx |
