Answer:
Slope =

Equation of the line →

Explanation:
Let the equation of diagonal OA is,
y = mx + b
Here, m = Slope of the line OA
b = y-intercept
Slope of a line passing through two points
and
is given by,
m =

Therefore, slope of the line passing through O(0, 0) and A(3, 4) will be,
m =

m =

Since, line OA is passing through the origin, y-intercept will be 0.
Therefore, equation of OA will be,
