Answer:
y = 1
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, 2) and (x₂, y₂ ) = (0, y)
m = , that is
=
( cross- multiply )
7(y - 2) = - 7 ( divide both sides by 7 )
y - 2 = - 1 ( add 2 to both sides )
y = 1
Given:
The graph of a linear inequality.
The boundary line passes through the points (0,-2) and (1,1), and the shaded region lies above the boundary line.
To find:
The inequality for the given graph.
Solution:
The boundary line passes through the points (0,-2) and (1,1), so the equation of the boundary line is:
Subtract 2 from both sides.
The boundary line is a solid line and the shaded area lies above the boundary line, so the sign of inequality must be .
Therefore, the required inequality is .
