Answer:
78i+52j
Step-by-step explanation:
8(9i+2j)-6(-i-6j)
72i+16j+6i+36j
=78i+52j
If -0.14 is changed to 2, the graph would become a positive graph, or it would be steeper, because it has a positive slope
The equation of the graph is given as:

The above equation is a linear equation, which is represented as:

Where m represents the slope of the linear equation.
By comparison, we have:

i.e. the slope of the equation
is -0.14
When -0.14 is replaced with 2, the equation becomes

And the slope of the new equation
is

2 is greater than -0.14, and 2 is positive.
This means that the graph would become a positive graph, or it would be steeper, because it has a positive slope
