Answer:
a = 1
Step-by-step explanation:
Given the point (a, 3) is on the line: 5x + y = 8.
Any point on the line satisfies the equation.
So, (a, 3) should satisfy the equation 5x + y = 8
Substituting x = a and y = 3, we get:
5(a) + 3 = 8
⇒ a = 1
Therefore, (1, 3) is the point on the line.
Answer:
(0, - 6)
Step-by-step explanation:
Since this is a vertical line then the midpoint of the y- coordinates is
(0 - 12) = - 6
⇒ midpoint = (0, - 6 )
