Answer 2

It seems like you have provided two equations:

1. Y = 5x - 12
2. y = 5x + 7

It's important to note that these equations use different variables for the dependent variable (Y and y) and are written in different cases (upper and lower case). It's a common convention to use capital letters for the dependent variable and lowercase letters for the independent variable, but this is not a strict rule.

If you are trying to find a point of intersection between these two equations (if they intersect at all), you can set them equal to each other since they both represent the same value of y:

5x - 12 = 5x + 7

Now, we can solve for x:

Subtract 5x from both sides: 5x - 5x - 12 = 5x - 5x + 7 -12 = 7

This equation does not have a valid solution since -12 is not equal to 7. Therefore, the two lines represented by the equations do not intersect, and there is no common point (x, y) that satisfies both equations simultaneously.

Visually, these two lines are parallel since they have the same slope (5) but different y-intercepts (-12 and 7). As parallel lines, they will never intersect.
