Need finding vertex of graph asap 12 point reward!

Finding the coordinates of the vertex is straightforward here, since we're given a good, clear diagram.

The vertex, in this case, is the lowest point of this graph. By counting from y-axis leftward, we see that the x-coordinate of the vertex is -4; by counting up to the y-axis, we see that the y-coordinate of the vertex is -4.

Thus, the vertex is located at (-4,-4).

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
