y+6= 11/20 x(x+1)

解

y + 6 = \frac{11}{20} x (x + 1)

(h, k) = (- \frac{1}{2}, - \frac{491}{80}), p = \frac{5}{11}

解答ステップ

y + 6 = \frac{11}{20} x (x + 1)

y + 6 = \frac{11}{20} x (x + 1)

を標準的な形式で書き換える

4 \cdot \frac{5}{11} (y - (- \frac{491}{80})) = (x - (- \frac{1}{2}))^{2}

ゆえに放物線の特性は:

(h, k) = (- \frac{1}{2}, - \frac{491}{80}), p = \frac{5}{11}
