Question

Thanks for helping plz lmk asap!

Answer 1

Your graph should be a horizontal line at point 8 lies on the y-axis

The equation is y= 8

Answer 2

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

`y = mx + b`

Where:

m: It's the slope

b: It is the cutoff point with the y axis

To find the slope two points are needed through which the line passes:

`m = \frac {y2-y1} {x2-x1}\\m = \frac {8-8} {- 5 - (- 2)} = \frac {0} {- 5 + 2} = \frac {0} {- 3} = 0`

THE equation is of the form:

`y = b`

We substitute the y coordinate of the point (2,8)

`8 = b`

Then,
`y = 8`

Answer:

`y = 8`
