`OR`
find x-intercept and y-intercept to graph by hand :=)

Answer 2

If the leading coefficient is positive then the right hand side of the graph will rise and left side will fall
If the leading coefficient is negative right end will fall and left end will rise

Answer 3

x-intercept is a point where line intersect x-axis when `y=0` so substitute y for 0 solve for x
y-intercept is a point where line intersect y-axis when `x=0` substitute x for 0 solve for y

Answer 4

factoring r by grouping
