Explanation:
To find the slope ( m ) 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# (x_1,y_1),(x_2,y_2)" are 2 coordinate points"# The 2 points here are (8 ,10) and (-4 ,-6)
let
# (x_1,y_1)=(8,10)" and " (x_2,y_2)=(-4,-6)#
#rArrm=(-6-10)/(-4-8)=(-16)/(-12)=4/3#
