Answer 2

The graph passes through the origin when:

1) The equation is 3x - 2y = a.

To determine if the graph passes through the origin for this equation, we need to substitute x = 0 and y = 0 into the equation and check if it holds true.

Substituting x = 0 and y = 0 into the equation 3x - 2y = a, we get:

3(0) - 2(0) = a 0 - 0 = a 0 = a

Since the equation holds true when a = 0, we can conclude that the graph passes through the origin when the equation is 3x - 2y = 0.

2) The equation is 5x + 3y = a - 2.

Similarly, we need to substitute x = 0 and y = 0 into the equation and check if it holds true.

Substituting x = 0 and y = 0 into the equation 5x + 3y = a - 2, we get:

5(0) + 3(0) = a - 2 0 + 0 = a - 2 0 = a - 2

Since the equation holds true when a = 2, we can conclude that the graph passes through the origin when the equation is 5x + 3y = 2.
