Question

.......... is the slope zero

Answer 1

Answer:

Step-by-step explanation:

OK... You have to use this formula: Y2 - Y1

                                                          X2 - X1

• -2 represents X1
• 7 represents Y1
• 2 represents X2
• -5 represents Y2    

Y2 - Y1

X2 - X1

-5 - 7

2 - - 2

-12

-2

Simplify by dividing both -12 & -2 by 2: -6

                                                                 -1

It's either -6 or it's just -6 by itself... Really sorry if I'm wrong...

                -1  

Answer 2

Well, a linear equation should look like this: y = ax + b.

So if the slope is 0, then y = a*0 + b = b.

If y = b, then the line is a horizontal line like this:    ______________

Now, we look at the points that were given in the question: (-2, 7), (2, -5)

If the slope is 0, then the value of y, should not change, but the value of x will constantly be changing. So it means that as x increases, y is always the same.

If we look at the y place on the points: The y values are the bold numbers:

(-2, 7), (2, -5)

As you can see, 7 is not the same as -5. So the line's slope is not 0. The slope would be a negative number. Why? Well, 7 is above the x-axis and -5 is below the x-axis. For the x values, -2 is smaller than 2, so the point (-2, 7) is located at the top left quadrant and the point (2, -5) is located at the bottom right quadrant.

So to answer your question, the slope is not zero. The slope is negative.
