In this case, we'll have to carry out several steps to find the solution.

Step 01:

data:

point 01 (4 , 2)

point 02 (6 , 5)

Step 02:

equation of the line:

slope:


m=(y2-y1)/(x2-x1)=(5-2)/(6-4)=(3)/(2)

Point-slope form of the line

(y - y1) = m (x - x1)


\begin{gathered} (y-2)=(3)/(2)(x-4) \\ \\ (y-2)=(3)/(2)x\text{ -}(12)/(2) \\ \\ y-2=(3)/(2)x-6 \\ \\ y=(3)/(2)x-6+2 \\ \\ y=(3)/(2)x-4 \end{gathered}

The answer is:

y = 3/2 x - 4
