Answer:
We can express the equation for any linear equation with slope -2 and point (x0,y0) as:
Step-by-step explanation:
Incomplete question:
There is no point to complete the equation.
As we have no point to complete the linear equation, we will solve for any given point (x0,y0) and a slope of m=-2.
The linear equation can be written generically as:
If a point, like (x0,y0) belongs to the linear equation, it satisfies its equation. Then:
Then, we can calculate b as:
We can express the equation for any linear equation with slope -2 and point (x0,y0) as:
