y = x +

Answer 1

@Mehek14

Answer 2

find the slope

Answer 3

\(\dfrac{9-1}{2-3}\)

Answer 4

-8/1

Answer 5

so -8

Answer 6

now you have y = -8x + ___

Answer 7

let's put b in the place after the +
y = -8x + b
you are going to solve for b
let's use the ordered pair (3,1)
\(1 = -8*3 + b\)

Answer 8

what is \(-8*3\)

Answer 9

-24

Answer 10

\(1 = -24 + b \\add~24\\ 24 + 1 = b\)

Answer 11

25

Answer 12

correct
so now your equation is
\(y=-8x+25\)
