Answer 1

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

$y\text{ - x = 7}$

solving for y, this is equivalent to:

$y\text{ = x+7}$

the line intersects the y-axis, when x = 0, thus replacing x= 0 into the above equation we get:

$y\text{ = 0+7 = 7}$

then, we can conclude that the line intersects the y-axis at the point:

$(x,y)\text{ = (0,7)}$
