Answer 1

Step-by-step explanation:

Hope It helps you

put the value of x and y at their respective places

Answer 2

Given:

Linear equation : 4x = ay + 8

The point (7, 5) lies on the graph

To Find:

The value of a

Solution

Given the point (7, 5):

⇒ x = 7, y = 5

Substitute x = 7, y = 5 into the equation to solve for a:

4(7) = a(5) + 8

28 = 5a + 8

5a = 20

a = 4

Answer: a = 4

----------------------------------------------------------------------

Additional notes:

If we substitute a = 4 into the equation:

⇒ we get 4x = 4y + 8

Recall that y = mx + c.

If we can rearrange the equation:

4x = 4y + 8

4y = 4x - 8

y = x - 2

From the equation, we can find out additional information:

⇒ gradient = 1

⇒ y-intercept = -2
