y = 5x + 6At the x-intercept, y = 0 .5x + 6 = 05x = -6x = -6/5
5x + y = 6 so that y = 6 - 5x Also x +2y = 1 so that x + 2*(6-5x) = 1 or x + 12 - 10x = 1 => 9x = 11 or x = 11/9 and then y = 6 - 5x = 6 - 55/9 = -1/9

what is 6 in 5x+6
y = 5x + 6At the x-intercept, y = 0 .5x + 6 = 05x = -6x = -6/5
5x + y = 6 so that y = 6 - 5x Also x +2y = 1 so that x + 2*(6-5x) = 1 or x + 12 - 10x = 1 => 9x = 11 or x = 11/9 and then y = 6 - 5x = 6 - 55/9 = -1/9
eqn1 5x - y = -6eqn2 -x + y = 2rearrange eqn1 to isolate yy = -1*(-6-5x)y = 6+5xsubstitute this into eqn2-x + 6 + 5x = 24x + 6 = 24x = -4x = -1substituting this into eqn1-5 -y = -6y = 1
It is slope intercept form. The equation for slope intercept form is y=mx+b which is like your equation y=5x+6
If you mean 5x+y = 21 and x = 6-2y then x = 4 and y = 1
The slope is -5

-5x + 6y = 24 6y = 5x + 24 y = 5/6 x + 4 the slope is 5 6
If x=6 and y=8, then [ 5x + 8y ] = 5(6) + 8(8) = 30 + 64 = 94
(6, -4)
x = 6, y = -4
If you mean y = 5x+6 then it is a straight line equation whereas 5 is the slope and 6 is the y intercept
