Definition
直线 (zhí xiàn) is a noun meaning 'straight line' and also an adjective meaning 'sharp, steep' for increases or decreases. As an adjective, it is more specific to sudden, linear changes than 陡 (dǒu) or 陡峭 (dǒu qiào), which describe physical steepness. The noun sense contrasts with 线条 (xiàn tiáo), which refers to lines in art or design, not geometry.
