You are correct with part i with what you did so far, but you need to finish it.
What is function f?

i.
$\dfrac{f(9) - f(2)}{9 - 2}$

ii.
$\dfrac{f(1) - f(0)}{1 - 0}$

iii.
$\dfrac{f(9) - f(-7)}{9 - (-7)}$

Line v passes through point [6.6] and is perpendicular to the graph of y= 3/4x - 11 line w is parallel to line v and passes thro

lbvjy [14]

Given:

The equation of a line is

$y=\dfrac{3}{4}x-11$

Line v passes through point (6,6) and it is perpendicular to the given line.

Line w passes through point (-6,10) and it is parallel to the line v.

To find:

The equation in slope intercept form of line w.

Solution:

Slope intercept form of a line is

$y=mx+b$ ...(i)

where, m is slope and b is y-intercept.

We have,

$y=\dfrac{3}{4}x-11$ ...(ii)

On comparing (i) and (ii), we get

$m=\dfrac{3}{4}$

So, slope of given line is $\dfrac{3}{4}$ .

Product of slopes of two perpendicular lines is -1.

$m_1\times m_2=-1$

$\dfrac{3}{4}\times m_2=-1$

$m_2=-\dfrac{4}{3}$

Line w is perpendicular to the given line. So, the slope of line w is $-\dfrac{4}{3}$ .

Slopes of parallel line are equal.

Line v is parallel to line w. So, slope of line v is also $-\dfrac{4}{3}$ .

Slope of line v is $-\dfrac{4}{3}$ and it passes thorugh (-6,10). So, the equation of line v is

$y-y_1=m(x-x_1)$

where, m is slope.

$y-10=-\dfrac{4}{3}(x-(-6))$

$y-10=-\dfrac{4}{3}(x+6)$

$y-10=-\dfrac{4}{3}x-\dfrac{4}{3}(6)$

$y-10=-\dfrac{4}{3}x-8$

Adding 10 on both sides, we get

$y=-\dfrac{4}{3}x-8+10$

$y=-\dfrac{4}{3}x+2$

Therefore the equation of line v is $y=-\dfrac{4}{3}x+2$ .

How to do this ? Wat or how do you work this out I need help this is due tmrw

velikii [3]

So first divide the equation on both sides by 3. We get $x - 2y = 4
$ . Slope-y-intercept form is of the form $y = mx + b$ . Rearranging $x - 2y = 4
$ , we get $2y = x - 4$ . Divide by two, we get $y = \frac{x}{2} - 2$ , which is of that form.

Graphing: The y intercept is at -2, and the slope is 1/2.
