"slope "=-2/5slope =−25

Explanation:

"calculate the slope m using the "color(blue)"gradient formula"calculate the slope m using the gradient formula

•color(white)(x)m=(y_2-y_1)/(x_2-x_1)∙xm=y2−y1x2−x1

"let "(x_1,y_1)=(3,-8)" and "(x_2,y_2)=(-7,-4)let (x1,y1)=(3,−8) and (x2,y2)=(−7,−4)

rArrm=(-4-(-8))/(-7-3)=4/(-10)=-2/5⇒m=−4−(−8)−7−3=4−10=−25
