The system of inequalities that best matches the graph is Option C
Step-by-step explanation:
To find the system of inequalities, we simply need to find the equation of each line.
Thus, let's find the inequality that is represented by each line.
Red Line:
First, let’s determine the slope. To do so, we can use the slope formula:
m = (y₂-y₁) / (x₂-x₁)
We can use any two points that's on the Red Line. Using (3, -2) and (6, -4) and substituting them into the slope formula yields:
m = (-4+2) / (6-3) = -2/3
Therefore, the slope of the red line is 2.
To write the equation of the red line, we can use the slope-intercept form:
y = mx + c
Notice that our y-intercept of our red line is (0, 3). Therefore, b = 3 and we already determined that m = -2/3:
y = ((-2/3)x) + (-3)
y = (-2/3)x -3
Now, we need to determine our sign. Notice that the shaded region is below the red line. Therefore, y is less than our equation.
And since our line is shaded, our sign will be less than or equal to. Therefore:
y ≤ (-2/3)x - 3
Blue line:
Again, let’s first find the slope. We can use the two points (3,0) and (0, -3). Hence:
m = (-3-0) / (3-0) = -3/3 = -1
So, the slope is -1.
We can now use the slope-intercept form. Notice that our y-intercept is (0, 0). Thus, we will substitute -1 for m and 0 for b. This yields:
y = -1x + 0
y = -x
Finally, we will determine our sign. Since the shaded region is above the blue line, our y is lesser than our equation. Therefore, our equation is:
y < -x
Thus, all together, our inequalities are:
y ≤ (-2/3)x - 3
y < -x
