How do you graph a line when your equation is written as a fraction?

Find the slope of the line that contains the following points. r(-2, 4), s(6, -2)

The formula for the lateral area of a right cone is la = rs, where r is the radius of the base and s is the slant height of the cone.which are equivalent equations?

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much
