Which polynomial is written in standard form?

Choice B)

-5x^3 + 9x^2 + 2x

Explanation:

Standard form is where the largest exponent term goes first, then the next largest, and so on. The exponents are decreasing when moving from left to right.

So that's why -5x^3+9x^2+2x is in standard form. Think of the 2x at the end as 2x^1. That might help show the exponents are decreasing (3,2,1).

The largest exponent is the degree, meaning that we have a third degree polynomial (aka cubic polynomial).

The first term -5x^3 is considered the leading term and -5 is the leading coefficient.

y=mx+b

step-by-step explanation:

m slope

b y-intercept

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
