1. The slope is the y-difference divided by the x-difference:
.. m = (5 -5)/(4 -(-3)) = 0
The slope of the line is 0.

2. In point-slope form, the equation is
.. y = -2(x -2) +3
Expanding to slope-intercept form, you have
.. y = -2x +7

3. You can start with point-slope form
.. y = 5(x -0) +2
.. 5x -y = -2 . . . . . standard form

4) The questions seem to relate to a parabola. The given equation is a linear equation. Perhaps you mean
.. y = -3x² +5x +7
a) the negative coefficient of x^2 tells you the graph opens downward.

b) The vertex x-coordinate is -5/(2*(-3)) = 5/6. The y-value of the vertex is
.. (-3*5/6 +5)*5/6 +7 = 5/2*5/6 +7 = 9 1/12
As an ordered pair, the vertex is (x, y) = (5/6, 9 1/12)

erik [133]
We know that

<span> the highest that this mountain can be is 27849 feet

because this number (27849 feet) rounded </span>to the nearest hundred is 27800 feet, however if the number were 27850 the number rounded to the nearest hundred would be 27900

hence

the answer is
27849 feet

PQ is bisected by line <em>L</em>.

so the answer is C

PQ=14

Step-by-step explanation:

5x-3=11-2x

5x+2x=11+3

7x=14

x=2

replace X in any of the given distance equation then multiply by 2 since the distance Pm=Qm

PQ=2(11-2x)

2(11-2(2))

2(7)

Therefore PQ=14
