The slope intercept formula is y=mx+b. M stands for the slope and y stands for the y-intercept. Therefore, since the slope is 6 and the y-intercept is -4, it can be written as: y=6x+(-4) which simplifies to y=6x-4.
Ask her why she is crying. If she explains why, listen and comfort her. If she says to "go away" or "i don't want to talk about it," give her space and come back later. She needs to let it out, so have patience :)
