the slope to determine if lines PQ and RS are parallel, perpendicular, or neither. P (0, -2), Q (0,7), R (3,-5), S (6,-5) Slope of PQ Slope of RS Types of Lines ​

answer: b.48 for

step-by-step explanation:

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

yes, i think so although i am not sure. this is a very strange question.
