Which of the lines graphed has a slope of one and a Y intercept of -3

there's not a picture

Step-by-step explanation:

But, if you connect the points (0,-3) and (3,0), there's the line

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
