You can put this solution on YOUR website!
The equation is y=2x%2B2 .
The x-intercept is the point (or the x-coordinate of the point in the x-axis) where y=0 .
In this case, for y=0 ,
2x%2B2=0--->%282x%2B2%29%2F2=0%2F2--->2x%2F2%2B2%2F2=o--->x%2B1=0--->x=-1 .
The x-intercept is the value -1 FOR x ,
or the point (-1.0).
The y-intercept is the point (or the y-coordinate of the point in the t-axis) where x=0 .
In this case, for x=0 ,
y=2%2A0%2B2=0%2B2=2--->y=2 .
The y-intercept is the value 2 for y ,
or the point (0,2).
Since two points uniquely determine a line,
you can use the two axis intercept points two graph the line.
You just plot the two points (on an x-y coordinate space), and connect them with a straight line:
