Find the Slope:

Answer:

4) slope= 0

5) slope =  -  \frac{1}{7}

Step-by-step explanation:

\boxed{ slope = \frac{y _{2} - y_1 }{x_2 - x_1} }

4) Slope

=  \frac{10 - 10}{ - 10 - 3}

=  \frac{0}{ - 13}

= 0

The slope is zero as the line is a horizontal line (since both points have the same y-coordinate of 10).

5) Slope

=  \frac{5 - 4}{2 - 9}

=  \frac{1}{ - 7}

=  -  \frac{1}{7}

Since you have taken (x₁, y₁) to be (9, 4), the value of x₁ should be 9 instead of 2.

<em>so, this is how I always do it as a little shortcut (it's the same as the formula, but it makes more sense lol):</em>

4) <u>0/13 = 0 = slope</u>

take your two points (-10, 10) and (3, 10) and just draw them relative to each other (it doesn't have to be to scale or anything)

. (-10, 10)           |     . (3,10)

                         |

                         |      

                         |    

------------------------------------------------

                         |

                         |

                         |

                         |

then, you just see how far up you go from (-10, 10) to get to (3, 10) --> look at the y-values, in this situation you <em>do not </em>go up or down, this means the "rise" for "rise/run" (slope) is 0

. (-10, 10)           |     . (3,10)

                         |

                         |      

                         |    

------------------------------------------------

                         |

then, you just see how far to the right you go from (-10, 10) to get to (3, 10) --> look at the x-values, in this situation you go over <u>13 units</u>, this means the "run" for "rise/run" (slope) is 13

take your "rise" and your "run" and divide: <u>0/13</u> = <u>0</u>**this is your slope because it is a horizontal line

5) <u>1/7 = slope</u>

follow the same steps as above (just a quick little sketch on paper)

(9, 4) and (2, 5)

rise = 1

run =  7

rise/run = <u>1/7 = slope</u>

The vertex of this parabola is at (-3, 6). Which of the following could be its equation?
pishuonlain [190]
Since the vertex is at (-3, 6), the equation is given by
y = a(x + 3) + 6

Therefore, option A is the correct answer.
