Answer 2

Answer:

a = 1

b = 3/2

Step-by-step explanation:

A = (3,5)

Let x = 3 and y = 5.

ax + by = 7

3a + 5b = 7          →           (1)

B = (1,4)

Let x = 1 and y = 4.

ax + by = 7

a + 4b = 7            →           (2)

(1) × 4

12a + 20b = 28    →           (3)

(2) × 5

5a + 20b = 35     →           (4)

(3) - (4)

12a + 20b - (5a + 20b) = 35 - 28

12a + 20b - 5a - 20b = 7

7a = 7

a = 1

From (2),

a + 4b = 7

1 + 4b = 7

4b = 7 - 1

4b = 6

b = 6/4

b = 3/2

The equation is x + 3/2 y = 7.

Hope this may be helpful.

Thank you. Have a nice day. :-)
