Graph each equation by using the y-intercept and slope

Mathematics
1 answer:
vitfil [10]3 years ago
6 0

Answers:

y intercept = -4

slope = -1

==========================================

Explanation:

The given equation is the same as y = -1x + (-4)

Compare this to y = mx+b form, and we see that

m = -1 is the slope

b = -4 is the y intercept

To graph y = -x-4, you could plot the two points (0,-4) and (1,-5) and draw a straight line through them. Extend the line as far as you can in either direction.

Notice how going from (0,-4) to (1,-5) follows the process "down 1, right 1" which is directly pulled from the slope = -1 =  -1/1.

Find the equation for the<br> following parabola<br> Vertex (-2,-4)<br> Focus (-4,-4)
iren [92.7K]

Answer:

None of the given option corresponds to the answer.

Step-by-step explanation:

The parabola has its axis of symmetry parallel to the x-axis and is represented by the following expression:

x - h = 4\cdot p \cdot (y-k)^{2}

Where:

h, k - Components of the vertex location, dimensionless.

p - Absolute distance of focus with respect to vertex, dimensionless.

The absolute distance is determined by following formula:

p = x_{F}-h

Where x_{F} is the horizontal component of focus with respect to origin.

If h = -2, k = -4 and x_{F} = -4, the absolute distance and the equation that represents the parabola is:

p = -4+2

p = -2

x +2 = -8\cdot (y+4)^{2}

None of the given option corresponds to the answer.
