Question

Which table was created using the equation y = 2x-1? PLEASE HELP!! QUICKLY

Answer 1

Answer:

A

Step-by-step explanation:

Plug the values into the equation

Answer 2

Option A is the correct answer.

If you look at the x and y values in table D, you’ll see that the change in y values is +2, while the change in x values is +1. Thus, the slope is 2/1 or 2.

Another way to look at it is by solving for the slope:

Using coordinates: (3, 5) (4 ,7):

Let x1 = 3

x2 = 4

y1 = 5

y2 = 7

$m = \frac{(y_{2} - y_{1}) }{(x_{2} - x_{1}) }$

$m = \frac{7 - 5}{4 - 3} = \frac{2}{1} = 2$

Therefore, the slope (m) = 2.

For the y-intercept, (b): it is the value of y when x = 0.

Let x = 0:

y = mx + b

y = 2(0) -1

y = -1

Therefore, the y-intercept is -1, which is also included in the given equation.
