1. Problem Description

The problem requires graphing the solution to the following system of inequalities:
y4x3y \ge 4x - 3
x+y7x + y \le 7

2. Solution Steps

First, we need to graph the line y=4x3y = 4x - 3. This is a line with slope 44 and y-intercept 3-3. We can find two points on the line to plot.
If x=0x = 0, then y=4(0)3=3y = 4(0) - 3 = -3. So, (0,3)(0, -3) is on the line.
If x=1x = 1, then y=4(1)3=1y = 4(1) - 3 = 1. So, (1,1)(1, 1) is on the line.
Since y4x3y \ge 4x - 3, we shade the region above the line y=4x3y = 4x - 3.
Second, we need to graph the line x+y=7x + y = 7. We can rewrite this as y=x+7y = -x + 7. This is a line with slope 1-1 and y-intercept 77. We can find two points on the line to plot.
If x=0x = 0, then y=0+7=7y = -0 + 7 = 7. So, (0,7)(0, 7) is on the line.
If x=7x = 7, then y=7+7=0y = -7 + 7 = 0. So, (7,0)(7, 0) is on the line.
Since x+y7x + y \le 7, or yx+7y \le -x + 7, we shade the region below the line y=x+7y = -x + 7.
The solution to the system of inequalities is the region where the two shaded regions overlap. The line y=4x3y = 4x - 3 is solid because the inequality is \ge. The line x+y=7x + y = 7 is solid because the inequality is \le.

3. Final Answer

The solution is the region where y4x3y \ge 4x - 3 and x+y7x + y \le 7. This is found by graphing the two inequalities and identifying the area of overlap.
