Suppose the x-intercept is a and the y intercept is b.

That is, the line passes through (a,0) and (0,b)

so the slope of the line is (b-0)/(0-a) = -b/a

Therefore, the equation of the line is y = -(b/a)x + b

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

How do you write an equation in slope intercept form with a given point?

Slope Intercept form is meant for a line, so if you know the slope m in the equation y=mx+b then with a given point say (3,4) and say the slope of the line was 2 then the equation would read y=2x+4.
