graph 2x+y=6
2x-y=-2
To graph linear equation, Slope - intercept form of the equation can help us.
y = mx + b, where m = slope and b = y-intercept
1. Rewrite 2x + y = 6 to slope intercept form
y = -2x + 6
m = -2 and b = 6 or y -intercept = 6, point is located (0,6)
To graph this Locate the first point (y-intercept) (0,6). With the help of
slope you will be able to find the second point. draw a line passing the
two points. m=-2 or -2/1 means move downward 2 units and 1 unit right
Look at the red line.
2. Rewrite 2x - y = -2 to y = mx + b
y = 2x + 2
m = 2 and b = 2, point located (0, 2)
Locate the first point (0,2). With the help of the slope 2, you will be able
to find the second point. Draw a line passing through the two points.
m = 2 or 2/1 means move 2 units upward and 1 unit to the right.
