"slope "=19/5slope =195

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)=(3,15)" and "(x_2.y_2)=(-2,-4)let (x1,y1)=(3,15) and (x2.y2)=(−2,−4)

rArrm=(-4-15)/(-2-3)=(-19)/(-5)=19/5⇒m=−4−15−2−3=−19−5=195
