Question

A line passes through the point(4,-1) and (2,3). What is the slope of the line

Answer 1

Slope is found using the equation (y2-y1)/(x2-x1)
So we can plug the numbers into the equation

(-1)-3/ 4-2
(-1)-3= -4
4-2=2 

The equation is now -4/2
-4/2= -2

So the slope of the line is -2

Which can also be written as y=-2x
