Question

find the value of a line 5y=ax+10,will pass through (1,3)

Answer 1

Answer:

5

Step-by-step explanation:

Let us assume that 5y= ax+ 10 passes through (1,3)

Then 5(3)= a(1)+10

15= a+10

a=5

Answer 2

Answer:

The given straight line is

5y = ax + 10 ...(i)

When the line (i) will pass through the point (2, 3),

5 (3) = a (2) + 10

➩ 15 = 2a + 10

➩ 2a = 15 - 10

➩ 2a = 5

➩ a =

Now, putting a = in (i), we get the required straight line as

5y = x + 10

➩ 10y = 5x + 20

Again when the line (i) passes through the point (1, 1),

5 (1) = a (1) + 10

➩ 5 = a + 10

➩ a = 5 - 10

Now, putting a = - 5 in (i), we get the required line as

5y = (- 5)x + 10

➩ y = - x + 2
