Help please, i really need it!

Answer 1

Explanation:

To find the slope, use 2 coordinates from your table and plug them into the slope equation, which is

`m=(y_(2)-y_(1)  )/(x_(2)-x_(1)  )`

Let's use the first 2 coordinates (-1, -2) and (0, -4). Plugging into the slope formula:

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

Therefore, we know that the slope is -2.

The y-intercept exists where x = 0. We see from our table that when x = 0, y = -4. So the y-intercept is -4.

To write our equation, we will use the slope-intercept form of a line, which is

y = mx + b, where m is the slope and b is the y-intercept. Plugging in both our values for slope and the y-intercept:

y = -2x - 4
