Here is a simple way to graph a linear equation. A linear equation is one that has a y term (a number times y), an x term and a constant (but no squares or cubes or square roots etc.):

Let x = 0 and use the equation to find y. This gives you one point on the graph: (0, -3)

Let y = 0 and use the equation to find x. This gives you another point on the graph (3, 0)

Plot these two points, join them with a line and extend in both directions.

However, this method gives only one point if the equation is of the form y = ax where a is some non-zero constant; and that point is (0,0)

In that case, use (1,a) as the second point.

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 does the shape of y equals x2 differs from the graph of y equals x3?

y = x2 is an (approximately) U shaped graph that is entirely above the x axis and is symmetric about the y axis. y = x3 is asymptotically negatively infinite when x is negatively infinite and positively infinite when x is positively infinite. It is symmetric about the line x+y=0.


Graph the equation y equals 8?

The graph of the equation y=8 is a horizontal line through the y-intercept of 8. This is because since y=8, any point on the graph will have a y-coordinate of 8. This is why it is a horizontal line through (0,8).
