Question

. Graphically, the pair of equations 7x – y = 5; 21x – 3y = 10 represents two lines which are (a) intersecting at one point (b) parallel (c) intersecting at two points (d) coincident​

Answer 1

Answer:

b)parallel

Step-by-step explanation:

Since slope of both lines is the same but y intercept is not the same.

7x-y=5

Slope = (1/7)

21x-3y=10

Slope = (3/21)=(1/7)
