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)

x-3y=4

step-by-step e

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
