A. y=-2x-4

b. y=2x-4

c. y=-4x+2

d. y=4x+2

B

Step-by-step explanation:

(x,y) so you have positive 2 for x, and on the y axis, the line goes through -4, so thats your y, so it will become y=2x-4

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
