Question

What is the value of P for which the graphical representation of the simultaneous equation 5x-3y=1 and py-2x=4 are parallel line.​

Answer 1

Answer:

:K can have any value except -12

Step-by-step explanation:

a1/a2 = b1/b2 not # c1/c2

5/2 = -3/-k # -1/4

Case 1,

5/2 = 3/k

6 = 5k

k = 6/5

Case 2,

3/k # -1/4

-k # 12

k# -12

Answer 2

Answer

To see whether or not two lines are parallel, we must compare their slopes. Two lines are parallel if and only if their slopes are equal. The line 2x – 3y = 4 is in standard form. In general, a line in the form Ax + By = C has a slope of –A/B; therefore, the slope of line q must be –2/–3 = 2/3.
