Explanation:
#"to calculate the slope use the "color(blue)"gradient formula"#
#color(red)(bar(ul(|color(white)(2/2)color(black)(m=(y_2-y_1)/(x_2-x_1))color(white)(2/2)|)))#
where m represents the slope and# (x_1,y_1),(x_2,y_2)" are 2 coordinate points"#
#"the 2 points here are " (8,7)" and " (2,-1)#
#"let " (x_1,y_1)=(8,7)" and " (x_2,y_2)=(2,-1)#
#rArrm=(-1-7)/(2-8)=(-8)/(-6)=4/3#
