It’s a. vertex is the lowest or highest point so (1,-8) x-intercepts is where the parabola hits the x axis so (-1,0) and (3,0)
You can subtract the 2x to make it -y=-2x-2 and add the x to make it -2y=x+4. for elimination method multiply the equation (-2)-y=-2x-2. Hope this helps. You can also do substitution method
