Answer:

y-intercept of the equation [tex]2x+y=4[/tex]  is [tex](0, 4)[/tex]

y-intercept of the equation [tex]-3x+9y=-6[/tex] is [tex](0,-\frac{2}{3})[/tex]

Step-by-step explanation:

Given:

The given equation are.

[tex]2x+y=4[/tex] ------------(1)

[tex]-3x+9y=-6[/tex] --------------(2)

We need to find the Y-intercept of given equations.

Solution:

Now we use the standard form of the line equation.

[tex]y = mx+c[/tex]

Where:

m = slope of the line

c = y-intercept of the line

First equation:

First we convert the equation 1 in standard form.

[tex]2x+y=4[/tex]

[tex]y=-2x+4[/tex]

So, y-intercept of the equation is (0, 4)

Second equation:

Convert second equation in standard form.

[tex]-3x+9y=-6[/tex]

[tex]9y=3x-6[/tex]

Divided by 9 both side of the equation.

[tex]y=\frac{3}{9}x-\frac{6}{9}[/tex]

[tex]y = \frac{1}{3}x-\frac{2}{3}[/tex]

So, y-intercept of the equation is [tex](0,-\frac{2}{3})[/tex]

Therefore, y-intercept of the equation [tex]2x+y=4[/tex]  is [tex](0, 4)[/tex]

y-intercept of the equation [tex]-3x+9y=-6[/tex] is [tex](0,-\frac{2}{3})[/tex]
