The equation to use is
y = mx + c

The first thing you need to know is the gradient represented by the m

Do you know how to find the gradient

Answer:

y = -3x² - 3x + 6

Step-by-step explanation:

main formula: r×(x² - (a + b)x + ab) = y

r×(x² - (-2 + 1)x -2×1) =y

r×(x² +x -2) = y

by using the point (0,6) →

r×(0² + 0 -2) = 6

r×-2 = 6

r= -3

so

y= -3x² -3x +6
