Question

Find the slope of the line that passes through (10,-8) and (1, 12). -20/9 4/9 20/0 9/4

Answer 1

Let's begin by identifying key information given to us:

`\begin{gathered} (x,y)=\mleft(10,-8\mright),(1,12) \\ slope(m)=(\Delta y)/(\Delta x)=(y_2-y_1)/(x_2-x_1) \\ slope(m)=(12-(-8))/(1-10)=(12+8)/(-9) \\ slope(m)=-(20)/(9) \end{gathered}`

Therefore, the slope of the line equal -20/9
