"slope "=-1/3slope =−13

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)=(9,8)" and "(x_2,y_2)=(6,9)let (x1,y1)=(9,8) and (x2,y2)=(6,9)

rArrm=(9-8)/(6-9)=1/(-3)=-1/3⇒m=9−86−9=1−3=−13
