Step-by-step explanation:
<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):
In this question, some of the data is missing so its a complete question and the solution can be defined as follows:
By given question, calculating equations are:
Putting the equation (c) value in the equation (a) to calculate value:
Putting equation (c) and (d) value into equation (b):
Putting m value into equation (c) and equation (d) to calculate its value:
Calculating the s value:
Calculating the r value:
So, the final value of "m, s, and r" are "900, 1800, and 5800".
