1. Here is a graph of the equation 2y - x= 1. y
a. Are the points (0,) and (-7,-3) solutions to the
equation? Explain or show how you know.
+
1
B6
2
3
b. Check if each of these points is a solution to the
inequality 2y - x> 1:
+
(0,2)
(-6,3) (-7,-3)
18.5)
c. Shade the region that represents the solution set to
the inequality 2y-r>I.
d. Are the points on the line included in the solution
set? Explain how you know.

(1 km=1000m, 1m=100 cm)

b) yes

step-by-step explanation:

let the statements be named as,

statement 1: if the power has been cut, then the refrigerator does not work.

statement 2: the refrigerator does not work.

conclusion: the power has been cut

now, 'law of detachment states that if we have the statements given as,

1. if p, then q.

2. p

then, we get the true statement or conclusion as q'.

thus, on comparing, we get that,

p: if the power has been cut.

q: the refrigerator does not work.

so, the argument is true by the law of detachment.
