Find the slope of the line.
Simple....we take two points on this line...in this case..(2,1) and (4,3)Using: \(\frac{ y_{1- y_{2}} }{ x_{1}- x_{2}}\)\(\frac{1-3}{2-4} = \frac{-2}{-2}=1\)Thus, your answer.
We can use the points (2, 1) and (4, 3) to solve.
Slope formula: y2-y1/x2-x1
= 3-1/4-2
= 2/2
= 1
Hope This helped! Good Luck!
