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)=(-3,4)" and "(x_2,y_2)=(2,-1)let (x1,y1)=(−3,4) and (x2,y2)=(2,−1)
rArrm=(-1-4)/(2-(-3))=(-5)/5=-1⇒m=−1−42−(−3)=−55=−1
