Answer:

undefined

Step-by-step explanation:

The equation for slope is:

\frac{y_{2} - y_{1} }{x_{2} - x_{1}}

We can plug in the given coordinates into the equation:

\frac{-7-(-1)}{-5-(-5)} =\frac{-7+1}{-5+5} =\frac{-6}{0}

The slope is undefined

Help me plss, number 2.​
Gnesinka [82]

Answer:

At (-2,0) gradient is -4 ; At (2,0) gradient is 4

Step-by-step explanation:

For this problem, we simply need to take the derivative of the function and evaluate when y = 0 (when crossing the x-axis).

y = x^2 - 4

y' = 2x

The function y = x^2 - 4 cross the x-axis when:

y = x^2 - 4

0 = x^2 - 4

4 = x^2

2 +/- = x

Hence, this curve crosses the x-axis twice, once at (-2,0) and again at (2,0).

The gradient at these points are as follows:

y' = 2(-2) = -4

y' = 2(2) = 4

Cheers.

15 - 4x = 6 - 3x<br><br>whats the answer. ​
Makovka662 [10]

Answer:9

Step-by-step explanation: First you add the 3x to both sides(the -4x and the -3x) and then you get 15-1x=6. Next you subtract 15 from 15 and 6, so you get -1x=-9. So then you divide both sides by -1 (do -1x over -1 equals -9 over -1). Last you do the dividing and you get x=9.
