Answer:
x ≤ 12.83
(Any number under or equal to 12.8333...)
Step-by-step explanation:
154 ≥ 12x
12.833.... ≥ x
x ≤ 12.83
The answer to Your question is 146.25

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.
A^2 + b^2 = c^2
4^2 + b^2 = 5^2
16 + b^2 = 25. -16
B^2 = 9
Square root of 9 = 3
B = 3
