Question

@Michele_Laino @borak

Answer 1

this like the first one;

Answer 2

you find the point the descriped in the formula

you find in the line or function (x1,-2)

Answer 3

the points are (1-2) and (2,2)

Answer 4

justs one (1,-2)

Answer 5

in the formula is write y-y1

Answer 6

then we can write:
\[2+2=m(2-1)\]
so:
\[m=4\]

Answer 7

the y1= -2 and x1 =1

Answer 8

can you explain more?

Answer 9

o.k the fromula have itself minus

Answer 10

if you see that written y- (-2) = m(x-x1);
that the y1 = -2 not to 2

Answer 11

because your line has to pass at point (2,2), and equation of your line, is:
\[y+2=m(x-1)\]
so, if I substitute the coordinates of point (2,2) into above equation, I have:
\[2+2=m(2-1)\]

Answer 12

you choose two point find the slope and the points in formula is (1,-2)

Answer 13

so would the answer be y-(-2)=4(x-2)
or
y-(-2)=4(x-1)

Answer 14

second one

Answer 15

no, please:
y-(-2)=4(x-1)

Answer 16

i do not know which one to give the medal too.. you guys both helped me out the same..

Answer 17

ok! I give a medal to @borak , and you give a medal to me, please

Answer 18

so the answer is y-(-2)=4(x-1)

Answer 19

the slope as you see 4 , yes the answer is right

Answer 20

THANK YOU SO MUCH GUYS!!!!!!! :)

Answer 21
