Conclusion:

-a-1 will be positive.

Step-by-step explanation:

Checking -a - 1

From the given line number, we can determine that

The value of a will be negative because it is located on the left side of the origin 0.

i.e. value of a > -2

so

-a - 1 will be positive because if we put the value a = -1.5 let say

then

-a - 1 = -(-1.5) - 1 = 1.5 -1 = 0.5

Therefore, -a-1 will be positive.

Checking -b + 2

As b > 2

putting b = 2.1        (taking the value of b slighly above than 2)

-b+2 = -2.1+2 = -0.1

Therefore, -b + 2 will be negative.

Conclusion:

-a-1 will be positive.

By definition, a linear equation in its standard form is given by:
 
 Where,
 m: slope of the line
 b: cut point with the y axis (occurs when x = 0)
 The value of m, b is constant.
 Therefore, the value of the rate of change of the function, which is represented by the slope of the line, is constant.
 This means that for each value of x, the value of the function increases m times.
 
 d.The change in y-values is constant for evenly spaced x-values.
