thats the form they gave you
now use the form and put your answers there

Answer 8

ok y= !/7x+3

Answer 9

how did you get that?

Answer 10

idk just guessed

Answer 11

why is there a question mark?

Answer 12

idk

Answer 13

ok i will explained it to youbut with different letters so you can do it and hopefully understand.

Answer 15

1) The standard form of the equation of the line passing through two points is:

Ax + By = C

2) You can find the equation of al line given two points in a two stages process:

i) Find the slope:

slope = m = [y₂ - y₁] / [ x₂ - x₁] = [1 - 2] / [5 - (-2) ] = - 1 / 7

Answer 16

ii) set the point slope equation:

y - y1 = m [x - x1]

y - 1 = (-1/7) (x - 5) -> 7 ( y - 1) = - (x - 5)

-> 7y - 7 = - x + 5 -> x + 7y = 5 + 7

-> x + 7y = 12

Answer 17

hope this helps

Answer 18

sorry it dones not

Answer 19

@kaleighh533 can u help me

Answer 20

@Mathmachine2021

Answer 21

@prettydevil45 i dunno how to do this one

Answer 22

mann

Answer 23

@SkilerLuke or @MiraAngel

Answer 24

I don't know im sorry

Answer 25

y=mx+b
m: slope
b: y-intercept
(7, 2)
(5, 4)
Slope:
(y2-y1)/(x2-x1)
(x,y)
(4-2)/(5-7)
2/-2
-1
y-intercept:
(see graph)
When x is 0, y is 9.
9
y=mx+b
y=-1x+9
