Question

the equations are written in point-slope form, which equation represents a line through points (-8,3)and (-2,-3)
a. y-3=1(x+8)
b. y-3=3(x+8)
c. y-3=-3 (x+8)
d. y-3=-1(x+8)
suppose you and some friends are going to the movies. the amount of money you spend for tickets varies directly with the number of people buying ticket , if you spend $48 for 6 tickets. what is the constant of varitoin?
a. 48
b. 8
c. 6
d. 1

Answer 1

first find the slope between the two points (-8,3) and (-2,-3)
can you do that?

Answer 2

no im bad a slopes

Answer 3

at

Answer 4

\[slope = \frac{ rise }{ run } = \frac{ y _{2}-y _{1} }{ x _{2}-x _{1} } \]when given points (x1, y1) and (x2, y2)

Answer 5

(-8,3) and (-2,-3)
Point slope form
M=y2-y1/x2-x1=-3-3/-2+8=-9/6=-3/2
y-y1=m(x-x1)
y-3=-3/2(x+8)

Answer 6

\[\frac{ -3-3 }{ -2-(-8) } =~?\]

Answer 7

2. y=kx

Answer 8

@corderoalize
-3-3 is not -9

Answer 9

Constant variation would be 8

Answer 10

Sorry it = -6

Answer 11

Sorry the slope would be -1

Answer 12

let's let @kate_bell do parts of it herself @corderoalize to make sure she understands the process

Answer 13

1. y-y1=m(x-x1)
y-3=-1(x+8)
2. y=kx
48=k(6)
8=k

Answer 14

They ask for help so we can give them the answers and help them through it so they can learn the process because your way is confusing

Answer 15

1. D
2. B

Answer 17

Ok but how many times have you repeated that because everyone does it

Answer 18

ahaha yep, so I have the copy-paste version xD @corderoalize

Answer 19

i got it yall
