<u>Exercise 3</u>



<u>Exercise 4</u>
a) If L2 is parallel to L1, it has the same slope (gradient) ⇒ 
If L2 passes through point (3, 1):



So L2 = L1
b) If L3 is perpendicular to L1, then the slope of L3 is the negative reciprocals of the slope of L1 ⇒ 
If L3 passes through point (-5, 2):



Answer:
2 5/12
Step-by-step explanation:
you can combine two fractions if they have the same denominator (bottom number) by adding the numerators (top numbers) and keeping the bottom number the same.
1/12+4/12 is the same as 1+4 you just put the sum over 12:
2 1/12+4/12= 2 5/12
it can also be written as 29/12
AC = x, CD = 2x cause of 30° angle. Use pythagoras then
