Which best describes the effect on the x-intercept of the graph of y=34x−3 if the slope is changed to −34 The x-intercept remains the same and the new line is translated upwards

The x-intercept becomes negative and the new line is parallel to the original line

The x-intercept remains the same and the new line is translated downward

The x-intercept becomes negative and the new line intersects the original line
