Plz help need answer ASAP

Answer 1

y =
`(1)/(2)` x + 4

Explanation:

Assuming you require the equation of the line.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

with (x₁, y₁ ) = (8, 8) and (x₂, y₂ ) = (10, 9)

m =
`(9-8)/(10-8)` =
`(1)/(2)` , then

y =
`(1)/(2)` x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (8, 8) , then

8 = 4 + c ⇒ c = 8 - 4 = 4

y =
`(1)/(2)` x + 4 ← equation of line
