Question

Find the slope of a line through points -1,-2 & -3,8

Answer 1

Answer:

$Slope(m)=-5$

Step-by-step explanation:

$Given \: two \: points \:(-1,-2)\: and \:(-3,8)$

$Here,\\x_{1}=-1,y_{1}=-2;\\and\:x_{2}=-3,y_{2}=8;$

$Now,\\Slope \:of \:a \:line \\joining \: given \:two \:points\\=(m)=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\=\frac{8-(-2)}{-3-(-1)}\\=\frac{8+2}{-3+1}\\=\frac{10}{-2}\\=-5$

Therefore,

$Slope(m)=-5$
