Question

akshay_budhkar · Answer

$$m={(y2-y1) \over (x2-x1)}$$

for slope of line passing through (x1,y1) , x2,y2) just substitute in it

anonymous · Answer

Let us assume there is an unknown point (x,y) between these two known points

(7-y)/(4-x) = (y-3)/(x-2)

Cross-multiply and simplify to get 
y = 2x-1

To check if this equation of the line is correct, plug in the x and y values of each of the known points to see if the equation holds

If it holds then the slope of the line is 2 (coeffecient of x)
