PLEASE HELP ME PLEASE Which statements accurately describe how to determine the y-intercept and the slope from the graph below?

On a coordinate plane, a line goes through points (0, negative 6) and (3, 0).

To find the y-intercept, begin at the origin and move horizontally to the graphed line. To find the slope, use two ordered pairs on the line and substitute them into the equation m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction.

To find the y-intercept, begin at the origin and move vertically to the graphed line. To find the slope, use two ordered pairs on the line and substitute them into the equation m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction.
