slope = - 1
Explanation:
To calculate the slope use the
#color(blue)"gradient formula"#
#color(red)(bar(ul(|color(white)(a/a)color(black)(m=(y_2-y_1)/(x_2-x_1))color(white)(a/a)|)))#
where m represents the slope and#(x_1,y_1),(x_2,y_2)" are 2 coordinate points"# The 2 points here are (-10 , -5) and (-8 ,-7)
let
# (x_1,y_1)=(-10,-5)" and " (x_2,y_2)=(-8,-7)#
#rArrm=(-7-(-5))/(-8-(-10))=(-2)/2=-1#
