Step-by-step explanation:
Substitute the x values from the table into the equation.
<u>Substitute -4 into the equation:</u>
y = -3(-4) + 4
y = 12 + 4
y = 16
<u>Substitute -2 into the equation:</u>
y = -3(-2) + 4
y = 6 + 4
y = 10
<u>Substitute 0 into the equation:</u>
y = -3(0) + 4
y = 0 + 4
y = 4
<u>Substitute 2 into the equation:</u>
y = -3(2) + 4
y = -6 + 4
y = -2
y = 16, 10, 4, -2
9 and -1
10 and -2
11 and -3
12 and -4
13 and -5
14 and -6
15 and -7

There are an infinite number of possible pairs that fit this description.
Area of Gobi desert = x
Area of Sahara = 7x (seven times the area of the Gobi)
7x+x=4000000
8x=4000000
x=4000000/8
x=500000
Gobi = 500000
Sahara =3500000
At least I think so, hope this helps.
