Question

Complete the equation describing how x and y are related. Please Help!!

Answer 1

y=2x-1

Explanation:

all work is shown and pictured

Answer 2

y = 2x - 1

Explanation:

`y=mx+b`

It's an equation of a line in the slope-intercept form.

m - slope

b - y-intercept → (0, b)

Choose any two ordered pairs (x, y) from the given table.

(0, -1) → b = -1, (2, 3).

Calculate the slope.

Use the formula:

`m=(y_2-y_1)/(x_2-x_1)`

Substitute the coordinates of the points:

`m=(3-(-1))/(2-0)=(4)/(2)=2`

Finally:

`y=2x-1`
