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)
As for example the perpendicular equation to line y = 2x+6 could be y = -1/2x+6 because the negative reciprocal of 2x is -1/2x
+ 1/8
The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph

Yes. 6 - y = 2x -y = 2x -6 y= -2x +6 If plotted on a graph, the line will have a gradient -2, and will intercept the axes at (0,6) and (3,0).

2x + 6y = 6Subtract 2x from each side:6y = -2x + 6Divide each side by 6:y = -1/3 x + 1The graph is a straight line, with a slope of [ -1/3 ], and intersecting the y-axis at the point [ y = 1 ].
A graph that has 1 parabolla that has a minimum and 1 positive line.

[ y = -2x + any other number ] is parallel to [ y = -2x + 6 ].

It is: -1/2x or as a decimal -0.5x
