In the coefficient is number in front of variable(s) thus it is -7.

That means either 5 or 6 and there are 6 possibilities thus,
the probability is

Not sure, what you want. Add to both sides to get,

Not sure what you want. You need to use F.O.I.L on which gives collect terms to get,

Slope-intercept form means basically solve for . First subtract 16 from both sides to get, now divide by 4 both sides to get,

First write it in slope-intercept form. Which is . Any line parallel to this one has the same slope. The slope in the coffecient of the which over here is 1 because .
