The system of inequalities that represents the shaded portion is
y ≤ -x + 4
y >
x
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-interceptThe rule of the slope is m =
, where
(x1, y1) and (x2, y2) are two points lie on the lineLet us find the equation of each line using the given figure
1. The solid line
∵ Points (4, 0) and (0, 4) lie on the solid line
∴ x1 = 4 and y1 = 0
∴ x2 = 0 and y2 = 4
→ Substitute them in the rule of the slope to find it
∵ m =![\frac{4-0}{0-4}=\frac{4}{-4}](/tpl/images/0921/1330/4788d.png)
∴ m = -1
∵ The line intersects the y-axis at point (0, 4)
∴ b = 4
∵ The line is solid and the shading is under the line
∴ The sign of inequality is ≤
∴ The inequality is y ≤ -x + 4
2. The dashed line
∵ Points (0, 0) and (3, 1) lie on the dashed line
∴ x1 = 0 and y1 = 0
∴ x2 = 3 and y2 = 1
→ Substitute them in the rule of the slope to find it
∵ m =![\frac{1-0}{3-0}=\frac{1}{3}](/tpl/images/0921/1330/9b93a.png)
∴ m =![\frac{1}{3}](/tpl/images/0921/1330/5506e.png)
∵ The line intersects the y-axis at point (0, 0)
∴ b = 0
∵ The line is dashed and the shading is over the line
∴ The sign of inequality is >
∴ The inequality is y >
x + 0
∴ The inequality is y >
x
The system of inequalities that represents the shaded portion is
y ≤ -x + 4
y >
x
