This equation is in vertex form. Vertex form is y=a(x-h)^2+k, where (h,k) is the vertex. In this equation, h= -3, and k= -4. So, the vertex would be at (-3,-4). A tells us if the parabola will be positive or negative. In this case, it is positive, so the parabola opens upward. Then, you can solve for x-intercept by letting y=0 and solving for x. Then, you can find the y-intercept by setting x=0 and solving for y. Finally, graph the parabola.

Answer:
y=x+1
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(3-2)/(2-1)
m=1/1
m=1
y-y1=m(x-x1)
y-2=1(x-1)
y-2=x-1
y=x-1+2
y=x+1
