What’s the slope of -2,-3 and -4,-9
Dmitry_Shevchenko [17]

Answer:

m = 3

Step-by-step explanation:

Find the slope of the line connecting (-2,-3) and (-4,-9).  (Note:  you must use those parentheses.)

As we go from x= -4 to x = -2, an increase of 2, y increases by 6 from -9 to -3.  The slope of this line is m = rise / run = 6/2 = 3.

If f(x) and its inverse function, F(x), are both plotted on the same coordinate plane, what is their point of intersection?
polet [3.4K]

Answer:  d) (3, 3)

<u>Step-by-step explanation:</u>

Inverse is when you swap the x's and y's.

Let's look at the points and find their inverse:

  f(x)           f⁻¹(x)

(0, -2)  -->  (-2, 0)

(1, -1)   -->   (-1, 1)

(2, 0)  -->   (0, 2)

(3, 3)   -->   (3, 3)       f(x) = f⁻¹(x) so this is where they intersect!
