The answer would be B hope I could help (: next time try to make it more explained (:
Answer:
this equation cannot be written in slope-intercept form
Step-by-step explanation:
The given equation is equivalent to ...
2x +9 = 0 . . . . . subtract 1x
x + 4.5 = 0 . . . . divide by 2
x = -4.5 . . . . . . . the equation of a vertical line.
It has no y-intercept and its slope is undefined.
Answer:
Radians

Step-by-step explanation:
Answer:
y = 1/6 x^2 + 8/3 x + 49/6
Step-by-step explanation:
This is a parabola which opens upwards.
The distance of a point (x, y) from the focus is
√[(x - -8)^2 + (y - -1)^2] and
the distance of the point from the line y = -4
= y - -4
These distances are equal for a parabola so:
√[(x - -8)^2 + (y - -1)^2] = y + 4
Squaring both sides:
(x + 8)^2 + (y + 1)^2 = (y + 4)^2
x^2 + 16x + 64 + y^2 + 2y + 1 = y^2 + 8y + 16
x^2 + 16x + 64 + 1 - 16 = 8y - 2y
6y = x^2 + 16x + 49
y = 1/6 x^2 + 8/3 x + 49/6 is the equation of the parabola.
