What equation represents the line that passes through points (1.-5) and (3 -17)?

zzz [600]

ALL LINES CAN BE REPRESENTED IN THE FORM $f(x) = ax+b$ .

We know that:

$f(1) = -5 \implies a\cdot(1)+b = -5 \implies a+b = -5$

and

$f(3) = -17 \implies a\cdot(3) +b = -17 \implies 3a+b = 17$

Observe that:

$3a+b = 2a+a+b = 2a+(a+b)$

So:

$2a+(a+b) =-17$

But we know that $a+b = -5$ , so:

$2a+(a+b) =-17$

$2a+(-5) = -17$

$2a = -12$

$a = -6$

Since:

$a+b = -5$

$(-6)+b = -5$

$b = 1$

So the line is:

$f(x) = 1-6x$

0.33%

= 0.33/100

= (33/100) / 100

= 33/(100*100)

= 33 / 10000 In its simplest form.

Answer:

< - 52, 48 > and 70.77

Step-by-step explanation:

2v - 6u

= 2<- 11, 3 > - 6 < 5, - 7 >

= < - 22, 6 > - < 30, - 42 >

= < - 52, 48 >

| 2v - 6u | = $\sqrt{(-52)^2+(48)^2}$ = $\sqrt{5008}$ = 70.77
