Answer:
Step-by-step explanation:
Assuming this is a linear equation in the form of , we can first solve for the slope using
, for these points, the slope would be
. Now we plug in the points to get the equation:
plugging in (7,5), we get ×
+
and solving for b, we get b =
therefore, the equation of the line passing through (7,5) and (1,2) is .
