Please help me how to graph and solve this problem

Answer: Infinite solutions
Step-by-step explanation:
y = -5x - 2 is in y = mx + b format.
The two points plotted above should be: (0, -2) and (1, -7)
y + 2 = -5x is not in y = mx + b format so subtract 2 from both sides.
y + 2 = -5x
- 2 - 2
y = -5x - 2 now it is in y = mx + b format
Notice that this is the same equation above that you already graphed because they are the same line.
The "solution" is where the lines intersect. Since these are the same line, there are infinite solutions.
