Answer to Problem 29E

The equation of the line parallel to L:y=x+2 and passing through the point P0,0 :

  y=x .

Explanation of Solution

Given:

Given a point P0,0 and a line L:y=x+2 .

Concept Used:

Slope-Intercept form of a line:

Suppose that the equation of a line is given in the slope-intercept form: y=mx+c .

Then, the m gives the slope of the line and c gives the y -intercept of the line.

Point-Slope equation of a line:

Given the slope m of a line and a point Px1,y1 through which the line passes, the Point-Slope equation of the line is as follows:

  y=y1+mxx1 .

Calculation:

Observe that the line L:y=x+2 is already in the slope-intercept form.

Compare y=x+2 with the general slope-intercept form and observe that the line has the slope m=1 .

Now, parallel lines have the same slope.

Thus, the line parallel to L:y=x+2 and passing through the point P0,0 will also have the slope m=1 .

Now, to find the equation of the line passing through the point P0,0 with slope m=1 , substitute m=1 and x1,y1=0,0 in the point-slope equation y=y1+mxx1 of a line:

  y=0+1x0 .

Simplify the equation y=0+1x0 :

  y=1xy=x .

Thus, the equation of the line parallel to L:y=x+2 and passing through the point P0,0 :

  y=x .

Conclusion:

The equation of the line parallel to L:y=x+2 and passing through the point P0,0 :

  y=x .

To determine

To write the equation of the line passing through the point P0,0 and perpendicular to the line L:y=x+2 .

Answer to Problem 29E

The equation of the line perpendicular to L:y=x+2 and passing through the point P0,0 :

  y=x .

Explanation of Solution

Given:

Given a point P0,0 and a line L:y=x+2 .

Concept Used:

Slope-Intercept form of a line:

Suppose that the equation of a line is given in the slope-intercept form: y=mx+c .

Then, the m gives the slope of the line and c gives the y -intercept of the line.

Slopes of perpendicular lines:

Suppose that two lines are perpendicular and that they have the slopes m and n . Then, it follows that, mn=1 .

Point-Slope equation of a line:

Given the slope n of a line and a point Px1,y1 through which the line passes, the Point-Slope equation of the line is as follows:

  y=y1+nxx1 .

Calculation:

Observe that the line L:y=x+2 is already in the slope-intercept form.

Compare y=x+2 with the general slope-intercept form and observe that the line has the slope m=1 .

Now, let the line perpendicular to L:y=x+2 and passing through the point P0,0 has the slope n .

Then, it follows that:

  mn=1 .

Substitute m=1 and find the value of n :

  1n=1n=1 .

Now, to find the equation of the line passing through the point P0,0 with slope n=1 , substitute n=1 and x1,y1=0,0 in the equation y=y1+nxx1 :

  y=0+1x0y=x .

Thus, the equation of the line perpendicular to L:y=x+2 and passing through the point P0,0 :

  y=x .

Conclusion:

The equation of the line perpendicular to L:y=x+2 and passing through the point P0,0 :

  y=x .
