7.) Write the equation 3x + 4y – 7 = 0 in normal form.

3/5x + 4/5y + 7/5 = 0

-3/5x - 4/5y - 7/5 = 0

-3/5x - 4/5y + 7/5 = 0 ~

3/5x + 4/5y - 7/5 = 0

8.)Write the standard form of the equation of a line for which the length of the normal is 4 and the normal makes an angle of 45° with the positive x–axis.

sqrt2x + sqrt2y +8 = 0

2x + 2y – 8 = 0

sqrt2x + sqrt2y -8 = 0 ~

2x + 2y + 8 = 0

9.) Write the standard form of the equation of a line for which the length of the normal is 3 and the normal makes an angle of 135° with the positive x–axis.

sqrt2^x – sqrt2y + 6 = 0 ~

sqrt2^x + sqrt2y - 6 = 0

sqrt2^x – sqrt2y - 6 = 0

sqrt2^x + sqrt2y + 6 = 0

10.) Find the distance between P (–2, 1) and the line with equation x – 2y + 4 = 0.

4sqrt5/5

0 ~

-4sqrt5/5

5/4
