Answer:
y=ax+1
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept
I cant see all the choices but its a quadratic function#
y=x-1
y=-2x-4
although I cant summon a graph for this one, I can give cords
for first graph (-2,-3),(-1,-2),(0,-1), (1,0),(2,1)
For second graph the slope is down 2 over 1, and begins at (0,-4).
(-2,0)(-1,-2),(0,-4),(1,-6),(2,-8)
