4a + 3b - a - 5b
First, gather the like terms.
Second, subtract 4a - a to get 3a.
Third, subtract 3b - 5b to get 2b.

Answer:
3a - 2b
The correct answer is C. A linear equation is written in y=mx+b, which this equation can be. y=3-4x is the same as y=-4x+3, which is a linear function.
Answer:
(7,0)
Step-by-step explanation:
In this question, we have to identify the zeros of the polynomial, along with a point, and then we get that the formula for the polynomial is:

------------------------
Equation of a polynomial, according to it's zeros:
Given a polynomial f(x), this polynomial has roots such that it can be written as: , in which a is the leading coefficient.
------------------------
Identifying the zeros:
Given the graph, the zeros are the points where the graph crosses the x-axis. In this question, they are:

Thus





------------------------
Leading coefficient:
Passes through point (2,-8), that is, when
, which is used to find a. So




------------------------
Considering the zeros and the leading coefficient, the formula is:
