Convert to slope-intercept form, y = mx + b.
Subtract 2x to both sides:
Divide 3 to both sides:
Now it's in slope intercept form, y = mx + b where 'm' is the slope. So the slope here is -2/3, which is Negative.
This is already in slope intercept form. So the slope here is 3, which is Positive.
For #3 and #4, take any two points from the table and plug them into the slope formula.
Let's take (0, 7) and (1, 5).
x1 y1 x2 y2
Subtract:
Divide:
So the slope is negative.
For #4, let's take (2, -8) and (3, -7)
x1 y1 x2 y2
Subtract:
Divide:
So the slope is positive.
The answer is the number farthest to the right. So 8

Answer:
(1) x(2/3) = y
(2) 27
(3) 8
(4) 9
Step-by-step explanation:
The first line of the table tells you how to fill in the second line. Use the x and y values from the third line to write (y/x) = (2/3). This gives you the equation ...
x(2/3) = y . . . . line (1)
For the remainder of the table, you can use the given value compared to the value in line 3 to see what the multiplier is for the other value.
(2): The multiplier is 18/2 = 9, so the missing x-value is 3×9 = 27.
(3): The multiplier is 12/3 = 4, so the missing y-value is 2×4 = 8.
(4): The multiplier is 6/2 = 3, so the missing x-value is 3×3 = 9.
