Answer: The approximate length of PQ is 10.8 unit.

Step-by-step explanation:

Here the coordinates of point P are (-3,7) and the coordinates of Q are (6,1)

Thus, by the distance formula,

The distance between the points P and Q is,

$PQ = \sqrt{(6-(-3))^2+(1-7)^2}$

$=\sqrt{(6+3)^2+(-6)^2$

$=\sqrt{9^2+ 36}$

$=\sqrt{81+36}=\sqrt{117}=10.8166538264\approx 10.8$

Thus, the approximate length of PQ is 10.8 unit.

F(x) = -4x + 8 find f(-4)

harina [27]

Answer:

f(-4)= 24

Step-by-step explanation:

-4(-4)+8 We need to multiply -4 and -4 and a negative times a negative is a positive.

16+8 Now it's easy math and we just add them

This gives us 24.

in the blanks below. Find the slope of the line passing through the points (-9, 2) and (9,2). slope:

user100 [1]

I will assume that we are trying to find the slope between (-9,2) and (9, 2)

The slope's equation ⇒ $\frac{y2-y1}{x2-x1}$

Let's set the variables:

(x1, y1) --> (-9, 2)

(x2, y2) --> (9, 2)

Now let's plug them in:

$Slope = \frac{2-2}{9--9} =\frac{0}{18} =0$

Thus the slope of the line is 0.

Hope that helps!
