y intercept is value of y when x = 0
x intercept is value of x when y = 0
if y intercept is twice x intercept then its value is twice as high
Mathematically, the standard form equation is y = mx + b where m = slope and b = y intercept
for x intercept let y = 0
0 = mx + b
x = -b/m = 1/2 y intercept = 1/2 time b
m = -2
y = -2x + b is the equation

What is the slope and yintercept of y plus 4x plus 3?
There is no slope nor intercept because there is no equation, simply an expression.
What is the xintercept for this linear equation 6x - y equals 9?
-3
What is the xintercept of y2x 5?
As written this is not a graphable thing. I does not represent a graphable equation because there is no "=" sign. Whatever the equation might be, the x intercept is found by setting y=0, which leaves you with an equation for x, which is the intercept.
