a line passes through the points in this table.\n\nwhat is the slope of the line?\n\nwrite your answer as an integer or simplified fraction.
Answer
Answer:
$- 2$
Explanation:
Step1: 选择两点
选点((7,23))和((8,21))。
Step2: 计算斜率公式
斜率公式为(m=\frac{y_2 - y_1}{x_2 - x_1})，这里(x_1 = 7,y_1 = 23,x_2 = 8,y_2 = 21)。
Step3: 代入计算
(m=\frac{21 - 23}{8 - 7}=\frac{-2}{1}=-2)。
