you have to get y by itself (y=mx+b form). subtract 4x from both sides of the equation. now you have y=-4x+6. start at the origin and go up 6 units. your m (slope) is -4 so go down 4 units and go over 1 unit.

One way would be to graph the two equations: the parabola y = x² + 4x + 3, and the straight line y = 2x + 6. The two points where the straight line intersects the parabola are the solutions. The 2 solution points are (1,8) and (-3,0)
x=5
Gosh... 4X plus 6 equals 30... This concludes to: 4X= 4 x X All you have to do is work back wards!!!! I'm only in year 6!! 30-6=24 Which mean 4 x X=24 X=6!!!!!!!!! =D
4x+2y = 6 2y = -4x+6 y = -2x+3 Perpendicular slope is 1/2
4x - 3 - 5x + 7 = 6 4x - 5x = 3 - 7 + 6 -1x = 2 x = -2
