The value of 4 is 4,000 (four thousand)
The formula for slope is
m= (y₂-y₁)/(x₂-x₁)
you can plug in the points that you are given to find the slope
m= (-1-2)/(2-(-4)
m= -3/6
the slope is -3/6 which reduced to -1/2
so the answer would be
c) -1/2
hope this helped!

3{-1 + 3 [ 7 - 2(-10 + 8)]} Work out ' inside' parentheses first:-
= 3{-1 + 3 [7 - 2*-2]}
= 3 { -1 + 3 [7 + 4]}
= 3 { -1 + 3*11}
= 3 * 32
= 96 answer
The answer is C: (-3,-1)
To test if points satisfy an equation, all you need to do is test the numbers in both of the equations it provides you
Here is proof the answer is C :
<em>y > x - 2 </em>
(lets plug in point C)
-1 > -3 - 2
<u>solve </u>
-1 > -5 <em>?</em>
<em>Yes</em> this statement is true- onto the next inequalitity!
<em>y > 2x + 2 </em>
-1 > 2(-3) + 2
<u>solve </u>
-1 > -6 + 2
-1 > -4<em> ? </em>
<em>Yes, </em>this inequality is true too!
Know we know answer c (-3,-1) is the right answer!
