Answer and Step-by-step explanation:
a - b = 2
=
b = a - 2
a = b + 2
______________
b = b + 2 - 2
b = b
______________
______________
a = a - 2 + 2
a = a
______________
If a equals 0, then the expression is undefined.
If b = 0, then the expression is 0.
There are infinite number of solutions when a is not 0 and the numbers are positive.

Step-by-step explanation:
Hello!
First, let's plot the points and draw a straight line through them (image).
Remember that a coordinate is given in the format of (x,y).
<h3 /><h3>Parts of a Line</h3>Equation format:
- m = slope
- b = y-intercept
The slope is how the graph changes in y as it does in x. Given our two points, the graph rises 2 units and runs 3. That means that the slope is .
The y-intercept is the intersection of the graph and the y-axis. The intersection takes place at y = -8, so the y-intercept is -8.
The equation is .
