3x-8y=-16 -5x-10y=7 give y intercept

3x-8y=-16

The y intercept is;

(0, 2)

-5x-10y=7

The y intercept is;

(0, -0.7)

Step-by-step explanation:

The y-intercept refers to the point where the graph of an equation intersects or crosses the y-axis. At this point, the corresponding value of x is 0.

From the first equation given;

3x-8y=-16

Substitute x with 0 in the equation and solve for y;

3(0) -8y = -16

-8y = -16

y = 2

The y intercept is thus;

(0, 2)

From the second equation;

-5x-10y=7

Substitute x with 0 in the equation and solve for y;

-5(0) - 10y = 7

-10y = 7

y = -0.7

The y intercept is thus;

(0, -0.7)

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.
