Answer:
Infinitely many solutions
Step-by-step explanation:
-5.9x - 3.7y = -2.1
5.9x + 3.7y = 2.1
If we add these two equations together, -5.9x cancels out 5.9x, -3.7y cancels out 3.7y, and -2.1 cancels out 2.1.
This leaves us with:
0 = 0
Since this is true, that means there are infinite solutions.
Equation of a line is g iven by y = mx + c; where m is the slope.
5 - 3x = 7 - 2x
-2x + 3x = 5 - 7
x = -2
The line is a vertical line and so has an undefined slope.
A is your answer since the x values change at a rate of +1 and the y values change at a rate of +4
