What are the x and y-intercepts of the line described by the equation? −6x+3y=18.9 enter your answers, in decimal form, plz explain

x - intercept is the point where the line crosses the x - axis.

We know that on x - axis , y - coordinate is zero

Given Line : -6x + 3y = 18.9

For finding x - intercept, We need to substitute y = 0 in the given Equation

⇒ -6x + 3(0) = 18.9

⇒ -6x = 18.9

⇒ x =

⇒ x = -3.15

⇒ x - intercept = -3.15

y - intercept is the point where the line crosses the y - axis.

We know that on y - axis , x - coordinate is zero

For finding y - intercept, We need to substitute x = 0 in the given Equation

⇒ -6(0) + 3y = 18.9

⇒ 3y = 18.9

⇒ y =

⇒ y = 6.3

⇒ y - intercept = 6.3

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.
