Question

Find the value of x so that the line passing through the points will have the given slope: (x, 6) and (10, -3) with a slope of -3/2.
A. -13
B. 4
C. 13
D. -12

Answer 1

@luckythebest
how do we do this ?

Answer 2

What is formula of slope?

Answer 3

Slope = y2-y1/x2-x1.

Answer 4

ok.
and slope given is -3/2

so -3/2 = y2-y1/x2-x1. try and solve. :)

Answer 5

what does y and x =

Answer 6

x1 = x, y1 = 6, x2 = 10, y2 = -3

and -3/2 = y2-y1/x2-x1

Solve for x.

Answer 7

i dont understand :( but ill try

Answer 8

-3/2 = -3-6/10-x

Answer 9

-3-6=-9

Answer 10

yep.

-3/2 = -9/10-x

-3(10-x) = 2.-9

at least now? :P

Answer 11

so x = 2.9 ? how did you get 2.9 ?

Answer 12

^ is the equation.

-3 x (10-x) = 2 x -9

i.e. -30 + 3x = -18

Answer 13

that what i got was 30 that why i asked you how you got 2.9

Answer 14

ok ok i get it. :P

2.-9 i meant 2 x -9 ( . means multiplication)

Answer 15

so now we have -9/-18 ?

Answer 16

Ok wait here.

-3/2 = -9/10-x

-3(10-x) = 2(-9)

=> -30 + 3x = -18

=> 3x = 12 i.e. x = 4.

Answer 17

ooooooooooooooooooo.
