Explanation:
"to calculate the slope m use the "color(blue)"gradient formula"to calculate the slope m use the gradient formula
•color(white)(x)m=(y_2-y_1)/(x_2-x_1)∙xm=y2−y1x2−x1
"let "(x_1,y_1)=(4,-5)" and "(x_2,y_2)=(-5,8)let (x1,y1)=(4,−5) and (x2,y2)=(−5,8)
rArrm=(8-(-5))/(-5-4)=13/(-9)=-13/9⇒m=8−(−5)−5−4=13−9=−139
