The y intercept is 6
The standard form for a straight line equation is y = mx + c, where 'm' is the gradient (slope) and 'c' is the y intercept when 'x' is zero. The equation for the line with details as shown in the question is y = -2x - 4
There is no particular property illustrated by the equation shown.
A linear equation is y = mx + c where m is the gradient and c is the y-intercept. Linear equations are always graphically shown as a straight line, regardless of the gradient or the y-intercept.

This is the identity property: the additive identity property of zero.
That must depend on the equation that has not been shown
The x-intercept is the point where the y-intercept is zero. "3x 5y 9" is not an equation. 3x+5y+9, or 3x-5y+9, are examples of what was meant to be shown.

To determine the x - intercept put y = 0 (and conversely the y - intercept is shown when x = 0) y = 4x + 6 0 = 4x + 6 4x = -6 x = -6/4 = -3/2 (or -1.5)
The x-intercepts are quite easy. Just write the equation: y = (x - 4)(x - 8) To get the desired y-intercept, you need to multiply this by a scale factor (a constant). Just calculate the y-intercept for the equation as shown above; that will show you by what constant you need to multiply (for example, if the y-intercept is 13, add a factor of 2, to get 26).
It is the additive identity property of zero. (n+0=n)
