Hitman42 [59]

Answer:

y = -3(x + 1)² + 9

Step-by-step explanation:

y = a(x - h)² + k, where (h, k) is the vertex

The vertex of the quadratic function is (-1, 9)

The only equation listed that has a vertex at (-1, 9) is:

y = -3(x + 1)² + 9

PLEASE HELP ASAP SLOPES OF PARALLEL AND PERPENDICULAR LINES
Kamila [148]

1) Parallel lines have equal slopes.

We need to find the slope of the given line by solving for y.

5x - 15y = 30

-15y = -5x + 30

y = (1/3)x - 2

The slope of the given line is 1/3, so the slope of the parallel line is also 1/3.

2) Line 1 has slope 2/3.

Line 2 has slope 2/3.

3) Line 1 is a vertical line through x = 2. Line 2 is a horizontal line through y = -5. The lines are perpendicular.

4) The given line can is solved for y, so we can see its slope is -5/2. The slopes of perpendicular lines are negative reciprocals. The perpendicular line has slope 2/5. We have point (5, 0) which is (x1, y1) in the slope-point formula.

y - 0 = (2/5)(x - 5)

y = 2/5 x - 2

5) The given equation has slope -3. To find the negative reciprocal, write the slope as a fraction, flip it, and change the sign.

Slope of perpendicular line is 1/3.
