Convert the function into intercept form. Show your work. y=-x^2+5x+36

UkoKoshka [18]

Y = -x2 + 5x + 36 → y = -(x2 -5x -36)

→ y = -(x2 - 9x +4x - 36)

→ y = -[x(x-9) + 4(x - 9)]

→ y = -(x - 9)(x + 4)

Your answer would be y=-(x-9)(x+4).

2 3 -3 -6 Please help

fgiga [73]

Find x-intercept and y-intercept

x-intercept = 3 → (3, 0)

y-intercept = -6 → (0, -6)

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

Substitute:

$m=\dfrac{-6-0}{0-3}=\dfrac{-6}{-3}=2$
