Question

PLEEEEASE. PLEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEASE help.

Answer 1

line l containts the points A(K+9, -4k-3) and B(-2,1) and has a y-intercept of 9. Find the value of k, the equation of the line L, and the coordiantes A

Answer 2

ok do you slope intercept form @Ferrariwindows7 ?

Answer 3

you have point (-2,1) and y intercept so u can easily find slope

Answer 4

no im 9. So can you just give me the answer? :/

Answer 5

when you get the slope use definition of slope to get k

\[\large slope =\dfrac{y_2-y_1}{x_2-x_1}\]

Answer 6

slope intercept form is

\[\large y=mx+c\]

where m is slope and c is y intercept

Answer 7

try to use the hints i gave and get to the solution : )

Answer 8

slope is
\[\frac{-4k-4}{k+11}\]
equation is
\[y=\frac{-4k-4}{k+11}(x+2)+1\]y intercept is what you get when \(x=0\) replace \(x\) by \(0\) and set all this much equal to 9, solve for \(k\)

Answer 9

first step is
\[\frac{-8k-8}{k+11}+1=9\]
second step is
\[\frac{-8k-8}{k+11}=8\]
third step
\[-8k-8=8(k+11)\]

Answer 10

divide by 8 and get
\[-k-1=k+11\] and you should be good from there

Answer 11

so -16k=96. K=-6?

Answer 12

and the equation of the line is y=4x+9
