what is the equation of the line that passes through the points (2,5) and (1,2)

Question

anonymous · Answer

First you can calculate out the slope of the line
$$\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }$$

Then using that slope you should be able to determine where the y intercept of that line is. From that information you can put the equation in y=mx+b form.
