"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)=(1,3)" and "(x_2,y_2)=(1,-2)let (x1,y1)=(1,3) and (x2,y2)=(1,−2)
rarrm=(-2-3)/(1-1)=-5/0→m=−2−31−1=−50
"since division by zero is undefined then slope is undefined"since division by zero is undefined then slope is undefined
Slope=undefined; vertical line
Explanation:
The slope is the change in the y-coordinates over the change in x-coordinates. The formula
The formula gives an undefined slope meaning that the line crossing the two points is vertical.
