You can put this solution on YOUR website!
the easiest way to do this is to convert each equation to the slope-intercept formula: y=mx%2Bb
in this formula, m=slope, b= y-intercept, & the x and y are the coordinates of any point on the graph.
just rearrange the equation to make it fit the formula.
1x%2B1y=2 converts to y=1x%2B2
1/1 is the slope (m), and 2 is the y-intercept (b), point (0,2)
after you plot the y-intercept, use the slope (rise/run) to find the next point
i hope this helps!
