Question

Using the equation, y=5x²−17x −12, determine the y-intercept.

A) (0, -12)
B) (4, 0)
C) (1.7, -26.4)
D ) (0, 12)

Answer 1

A

Explanation:

to find the y- intercept let x = 0 in the equation and solve for y

y = 5(0)² - 17(0) - 12 = 5(0) - 0 - 12 = 0 - 12 = - 12

then the y- intercept is (0, - 12 )

Answer 2

`\huge\boxed{\sf (0,-12)}`

Explanation:

Given equation:

`y=5x^2-17x-12`

y-intercept is the point where x = 0

Put x = 0 in the above equation.

`y=5(0)^2-17(0)-12\\\\y = 0-0-12\\\\y=-12`

So, y = -12, when x = 0.

Ordered pair = (x,y) = (0,-12)
