PLEASE HELP I WILL MARK

The answer is C

Step-by-step explanation:

We apply the given formula: y= 2x + 1.

0 x 2 = 0 + 1 = 1, so A is incorrect.

1 x 2 = 2 + 1 = 3, C is the only one with 3 as the second number, so C is correct

m = -1/3

Step-by-step explanation:

First, write the equation in slope-intercept form:

3y = 10 - x

y = 10/3 - x/3

y = 10/3 - 1/3x

Since our slope is the coefficient of the x term, our slope is -1/3.
