Answer:
Solution given:
[tex](x_1,y_1)=(1,8)[/tex]
[tex](x_2,y_2)=(4,7)[/tex]
now
slope [m]=[tex]\frac{y_2-y_1}{x_2-x_1}=\frac{7-8}{4-1}=\frac{-1}{3}=-⅓[/tex]
let's find the slope of the line passing through given points :
- [tex] \mathrm{ \dfrac{y_2 - y_1}{x_2 - x_1} }[/tex]
- [tex] \mathrm{ \dfrac{8 - 7}{1 - 4} }[/tex]
- [tex] - \dfrac{1}{3} [/tex]
