(1,2), (3,5)
给出两个点的直线的方程.
首先,我们将使用公式来找出直线的斜率 (`m`),使用公式, (`m = (y2 - y1) / (x2 - x1) `,其中 (x1,y1) 是第一点, (x2,y2) 是第二点.将点的值置于公式中: `m = (5 - 2) / (3 - 1) `,从而得到 `m = 3/2 `.接下来,我们将使用点斜率形式来找出直线的方程.点斜率形式由 `y - y1 = mx - x1) `,其中 m 是斜率,而 (x1,y1) 是两个点之一.我们可以使用点,让我们选择第一点, (1,2) 换成公式: `y = (2x3) ⋅x2 (x2) ⋅x3 (2x3) ⋅x2 (2x2) ⋅x3 (2x2) ⋅x3 (2x3) ⋅x2 (2x2) ⋅x3 (2x2) ⋅x3 (2x3) ⋅x2 (2x2) ⋅x3 (2x2) ⋅x3 (2x3) ⋅x2 (2x2) ⋅x3 ⋅x3) ⋅x2 (2x2) ⋅x3 ⋅x3) ⋅x2 (2x2) ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅x2 ⋅2 ⋅2 ⋅2 ⋅2 ⋅2 ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ ⋅
