A line passes through the point (0, 1) and has a positive slope. Which of these points could that line NOT pass through? Check a

Vinvika [58]

We have to find slopes one by one.

$\\ \sf\longmapsto Slope=m=\dfrac{y_2-y_1}{x_2-x_1}$

(0,1)
(12,3)

$\\ \sf\longmapsto \dfrac{3-1}{12-0}$

$\\ \sf\longmapsto \dfrac{2}{12}$

$\\ \sf\longmapsto \dfrac{1}{6}>0$

Line passes through this.

(-2,-5)

$\\ \sf\longmapsto \dfrac{-5-1}{-2-0}$

$\\ \sf\longmapsto \dfrac{-6}{-2}$

$\\ \sf\longmapsto 3>0$

Line passes through this

(-3,1)

$\\ \sf\longmapsto \dfrac{1-1}{-3-0}$

$\\ \sf\longmapsto \dfrac{0}{-3}=0$

Not possible (Line passes through y axis as one co-ordinate is (0,1))

( 1,15)

$\\ \sf\longmapsto \dfrac{15-1}{1-0}$

$\\ \sf\longmapsto \dfrac{14}{1}$

$\\ \sf\longmapsto 14>0$

Line passes through this

(5,-2)

$\\ \sf\longmapsto \dfrac{-2-1}{5-0}$

$\\ \sf\longmapsto \dfrac{-3}{5}$

Line doesnot pass through this.

Alona [7]

Answer:

Step-by-step explanation:

you can see this is a geometric progression which a ratio of ${2\over{5}}$ . the sum of the firs n term is:

$S=a_1\frac{(1-r^n)}{(1-r)}=175\frac{1-(\frac{2}{5})^{10}}{1-\frac{2}{5}}=291.6360832$

the nearest integer would be:
