Y=mx + b
3x-4y=12
4y=3x-12
y=3/4x-3

when x = 0, y = -3
when y = 0, x = 4

Hope this helps.

x-intercept can be found when y=0
y-intercept can be found when x=0

Plug in x=0 to find the y-intercept
-3(0) + 4y = -12
4y = -12
y = -3

<span>Plug in y=0 to find the x-intercept

</span>-3x + 4(0) = -12
-3x = -12
x = 4

The x-intercept is (4,0)
The y-intercept is (0, -3)

The graph of the equation x=y2+4is symmetric with respect to which of the following

lyudmila [28]

Answer:

The x-axis

Step-by-step explanation:

The graph of the equation x=y2+4 is symmetric with respect to the x-axis.

To test for symmetry with respect to the x-axis we substitute -y in place of y and simplify the equation. If the resulting equation is identical to original one then the function is symmetric with respect to the x-axis;

$x=y^{2} +4\\x=(-y)^{2} +4\\x=y^{2} +4$

which is identical to the original equation

I need to figure this out cause idk.

Since she flipped the coin 20 times and got 4 heads and 6 tails, you put it as a fraction. So, it's 4/16 if you simplify 4 over 16 you get 1/4. You get this by dividing by 4 both numbers.
