Answer: The axis of symmetry = 1

That's a vertical line passing through 1 on the x-axis

Step-by-step explanation: From standard form, ax² + bx + c

Use the values of a and b in the equation x = -b/2a to find s, the axis of symmetry.

x = -(-6)/2(3)

x = 6/6

x = 1

Find the slope of the line that passes through the points (3,0) and (3,-2).

Fittoniya [83]

When given the points (x1,y1) and (x2,y2)

slope=(y2-y1)/(x2-x1)

we have
(3,0) and (3,-2)
(x,y)
x1=3
y1=0
x2=3
y2=-2

slope=(-2-0)/(3-3)=-2/0=undefined since you caon't divide by zero
