    对于线性方程\(y = a + bx\)，\(b\)= 斜率和\(a = y\)-截距。 从代数来看，斜率是一个描述直线陡度的数字，而\(y\)-intercept是直线与y轴\((0, a)\)交叉点的\(y\)坐标。 从微积分来看，斜率是函数的一阶导数。 对于线性函数，斜率是我们可以将数学表达式理解为 “由变化引起的 y (dy) 的变化\(x (dx) = b * dx\)”\(dy / d...对于线性方程\(y = a + bx\)，\(b\)= 斜率和\(a = y\)-截距。 从代数来看，斜率是一个描述直线陡度的数字，而\(y\)-intercept是直线与y轴\((0, a)\)交叉点的\(y\)坐标。 从微积分来看，斜率是函数的一阶导数。 对于线性函数，斜率是我们可以将数学表达式理解为 “由变化引起的 y (dy) 的变化\(x (dx) = b * dx\)”\(dy / dx = b\) 的地方。
