Question

Which equation is a point-slope form of the equation of this line?

a. -2x+y+5=0
b. y=2x-5
c. (y+1)=-1/2(x-2)
d.(y-1)=2(x+2)

Answer 1

@Janu16

Answer 2

slope = (7-1)/(1-(-2)) = 2
y1 = 1
x1=-2

required equation => y-y1 = slope*(x-x1)

put it there find ur answer

Answer 3

Im still lost

Answer 4

(x1,y1) = (-2,1)
(x2,y2) = (1,7)

slope = y2-y1 / x2-x1

point slope form =>y-y1 = slope*(x-x1)

u have everything there just insert it in the equation...

Answer 5

ok a and b are off and letter c has the line going other way so its D

Answer 6

@meganbeth1998

Answer 7

wait no its not D

Answer 8

its d

Answer 9

wait its is

Answer 10

princeharry explained it well

Answer 11

thanks @Janu16 and @texaschic101 and @princeharryyy

Answer 12

y-1 = 2 (x+2)
