8. Line AB passes through A(-2,4) and B(-8,-6).

netineya [11]

Answer:

AB : $\frac{5}{3}$

PT : $-\frac{1}{5}$

Step-by-step explanation:

The line AB passes through A(-2,4) and B(-8,-6) points.

Therefore, the slope of the line AB will be $\frac{4-(-6)}{-2-(-8)} =\frac{5}{3}$ (Answer)

Again line PT passes through P(3,-1) and T(8,-2) points.

Therefore, the slope of the line PT will be $\frac{-1-(-2)}{3-8} =-\frac{1}{5}$ . (Answer)

Here we have applied the formula of slope of a straight line passing through the points $(x_{1},y_{1})$ and $(x_{2},y_{2} )$ as given by $\frac{y_{1}-y_{2} }{x_{1}-x_{2} }$ .
