Question 974870
Determine the equation of a parabola with vertex (-2,-11) and point (-4,5)show answer in vertex form.
vertex form of equation : y=mx+b, m=slope, b=y-intercept
slope ∆y/∆x=(5-(-11))/(-4-(-2))=16/-2=-8
equation: y=-8x+b
solve for b using coordinates of given point (-4,5) on the curve
b=y+8x=5+8*-4=-27
equation=y=-8x-27
