Which graph represents the system of inequalities?
Solution
Solution Steps
Step 1: Analyze the first inequality
The first inequality is \(y < 2x + 4\). The line will have a slope of 2 and a y-intercept of 4. It will be a dashed line since it's a strict inequality (\(< \)). The shading will be below the line because \(y\) is _less than_ the expression.
Step 2: Analyze the second inequality
The second inequality is \(y \le -\frac{1}{2}x - 3\). The line will have a slope of \(-\frac{1}{2}\) and a y-intercept of -3. It will be a solid line because it's a less than or equal to inequality (\(\le \)). The shading will be below the line because \(y\) is _less than or equal to_ the expression.
Step 3: Compare to the graphs
We are looking for a graph with a dashed line with slope 2 and y-intercept 4, and a solid line with slope \(-\frac{1}{2}\) and y-intercept -3. Both inequalities are shaded below their respective lines, so the overlapping shaded region will be where both conditions are true. The only graph that matches these criteria is graph X.
