|f(a)| , the vertical lines mean absolute value. Absolute value is the positive value of the answer whether it is actually negative or positive.

F(a) is given as -5, so the absolute answer would be 5

The answer is 5

Write an equation of the line that is perpendicular to 3x + 9y = 7 and passes through the point (6, 4).

musickatia [10]

Hi there!

The equation of any line perpendicular to
$ax + by = c$
is
$bx - ay = c$

Therefore, in this situation, the formula of the line would be
$9x - 3y = c$

Given that the line passes through the point (6, 4) we get
$9 \times 6 - 3 \times 4 = c$
$54 - 12 = c$
$c = 44$

Therefore, the equation of the line that is perpendicular to 3x + 9y = 7 and passes through (6, 4) is
$9x - 3y = 44$

Can you find the slope and type the correct code?

AnnyKZ [126]

Answer:

1. (3,19) and (-1,-13)

to find the slope you need to do $\frac{y2-y1}{x2-x1}$

Hence $\frac{-13-19}{-1-3}$ = 32/-4=-8

2. Take two points on the graph:

(-2,3) and (1,0)

Know that to calculate the slope you do

$\frac{rise}{run}$ = 4/2= 2

3. To find the slope in a table you need to choose any two points and utilize the following formula: $\frac{y2-y1}{x2-x1}$ = $\frac{-16-(-8)}{2-1}$ =-8/1= -8

4. Like in #1 we take the two points and plug it into the formula:

$\frac{8-(-10)}{0-9}$ =18/-9= -2
