Answer:

A = -1

So, option (B) is the correct answer.

Step-by-step explanation:

The two points on line have coordinates: p (x₁, y₁) = (0, A) and q(x₂, y₂) = (2 , -3)

Slope of line = A

Slope of line = \frac{y_{2} - y_{1}}{x_{2} -x_{1}}

Now since the slope of line is A  and its has two coordinates (0, A) and (2 , -3), ∴

A = \frac{y_{2} - y_{1}}{x_{2} -x_{1}}

A = \frac{-3 - A}{2 - 0}

2A = -3 - A

2A + A = -3

3A = -3

A = -1

So, option (B) is the correct answer.
