how to know if i have to subtract or add in a point slope form? for example the part where it says (x - 1) how would i know if its (x - 1) or (x + 1)

Step-by-step explanation:

the general formula is

(y-y1)=m(x-x1) where

m is the slope

(x1, y1) are the coordinate of one point that belongs to the line

(x,y) are just variables

If you are given point (-3,4) and slope 2 for example the equation is

m=2, (x1, y1)=(x1=-3, y1=4)

so the equation is

(y-4) = 2(x-(-3)) so is

(y-4) =2(x+3)

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.

step-by-step explanation:

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
