The only coefficient here is just 1
slope = coefficient of x = -4
The coefficient of X is 1
Slope = coefficient of x = 8
When equation of line is y=-4x+3, Gradient is -4 (as seen from the coefficient of x) and the y-intercept is +3 (point where x=0)
Sure does.
2x-4
x(x+4) equals x2 plus 4x
If the x=4, then its equivelent to 12 + 4, which equals 16.
The 4.
symmetric property
4
y equals x plus 4 when y equals 0 then x equals 2i i is the square root of negative 1
