He l p m e. you : ). this quiz has my head messed up in multiple ways, american teachers don't play around. and yes i am listening to big time rush

the answer to your question is:

a) the third option is correct

b) the last option is correct

step-by-step explanation:

a) a (-2, 15) b (9, -18)

slope     m = (y2 -y1) / (x2 - x1)

              m = (-18-15) / (9+2)   substitution

              m = -33/11                 simplify

              m = -3

point slope form

          y - y1 = m(x - x1)

          y - 15 = -3 (x -2)       substitution

b) (8, -8) slope = 3

        y + 8 = 3(x - 8)           substitution

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

answer:

a=9
