Step-by-step explanation:
3x - 3x -y + 3y = 27-1
2y = 26
y = 13 use this to find the value of x
3x - 13 = -1
3x = -1 + 13
3x = 12
x = 4

Answer:
y ≤ x - 1
Step-by-step explanation:
The slope is 1 (every unit for x, there is a unit for y, rise/run is 1/1). The y-intercept is -1, because the line crosses the y-axis at -1. The graph is shaded below the line, and the line is solid, meaning that y is less than or equal to x -1, or y ≤ x - 1.
