Answer:
B. you can check the second one
We can use the points (10, -11) and (10, -2).
Slope formula: y2-y1/x2-x1
= -2-(-11)/10-10
= 13/0
Since the denominator is 0, the slope is undefined.
Best of Luck!
Given the equation of parabola: y = -x² - 2x - 5
y = ax² + bx + c and negative value of 'a' tell us that it is a downward open parabola whose axis of symmetry would be x = k.
where k is the x-coordinate of vertex of given parabola.
Finding the vertex of parabola, x =
So, the axis of symmetry for this parabola is x = -1.
its 1200 i think i work it out but i could have done it wrong
