Hi
the following are linear equations representing lines on a graph
I. Can find points(x,y) on these lines by sustituting values of x
y = 2x+2  |Pt(0,2) and Pt(1,4) are two points on this line
y = x-3   |Pt(0,-3) and Pt(1,-2) are two points on this line
II.Plotting these points, one can the draw lines thru them representing the equation
for example: green is y = 2x+2 and blue is y = x-3
{{{drawing(300,300, -6, 6, -6, 6, grid(1),
circle(0, 2,0.3),
circle(0, -3,0.3),
circle(1, 4,0.3),
circle(1, -2,0.3),
graph( 300, 300, -6, 6, -6, 6,0,2x+2,x-3))}}}
