which of the following equations has a graph that crosses the y-axis at a point lower than the graph of y=2x^-1

a.) y= -3x^2-1
b.) y= -3x^2+1
c.)y= -3^2+3
d.)y= 3x^2-3

step-by-step explanation:

step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
