Use the quadratic equation y = x^2 – 6x + 9.
where does the vertex of the parabola lie?
a. below the x-axis
b. on the x-axis
c. on the y-axis
d. above the x-axis
calculate the discriminant to determine the number of real roots.
y = x^2 + 3x + 9
how many real roots does the equation have?
a. one real root
b. no real roots
c. two real roots
d. no solution to the equation

true? is that what you're asking or do you mean something else?

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
