Problem: Adrienne graphs the line y-x=7. At what point will the line intersect the y-axis? at the point =(_,_)
Solution:
Consider the line
[tex]y\text{ - x = 7}[/tex]solving for y, this is equivalent to:
[tex]y\text{ = x+7}[/tex]the line intersects the y-axis, when x = 0, thus replacing x= 0 into the above equation we get:
[tex]y\text{ = 0+7 = 7}[/tex]then, we can conclude that the line intersects the y-axis at the point:
[tex](x,y)\text{ = (0,7)}[/tex]
