The slope of diagonal OA IS__,
and its equation is__

--- slope of OA

--- the equation

Step-by-step explanation:

Given

The attached graph

Solving (a): Slope of OA

First, we identify two points on OA

So, the slope (m) is:

This gives:

Solving (b): The equation

This is calculated as:

Recall that:

So, we have:

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
