In the form of , find the equation of the straight line that intersects the positive part of the -axis at a point that is 1 unit length away from the origin, given that the straight line is parallel to another line whose equation is .
For straight line graphs,
where is the slope and is the -intercept.
The -intercept, , is the point where the line intersects the -axis which we know is 1 from the question.
So we can say,
Our line must be parallel to the line with equation
The equation can be rearranged to get
The slope, , of this line is . So, for our line to be parallel to this one, it must also have a slope of .
Thus, the equation is .
