Answer:

<u>B. 1/2 and 1.</u>

Step-by-step explanation:

The coefficient of a variable is the number that the variable is being multiplied for. In this example. We can see that x² is being multiplied by 1/2, therefore <u>1/2 is one of the coefficients</u>.

In the case of x, it doesn't have a number before it, it means that it's being multiplied by 1. Hence, our <u>second coefficient is 1</u>.

What is the slope of the line ?(khan academy)
Ad libitum [116K]

Answer:

The slope of the line is 2.

Step-by-step explanation:

Slope of a line:

Suppose that we have two points. The slope of the line is given by the change in y divided by the change in x.

In this question:

Points (0,0) and (1,2)

Change in y: 2 - 0 = 2

Change in x: 1 - 0 = 1

Slope: m = \frac{2}{1} = 2

The slope of the line is 2.
