Answer 1

y = -
`(2)/(5)` x + 5

Explanation:

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 ) = (5, 3) and (x₂, y₂ ) = (10, 1) ← 2 points on the line

m =
`(1-3)/(10-5)` =
`(-2)/(5)` = -
`(2)/(5)`

The line crosses the y- axis at (0, 5) ⇒ c = 5

y = -
`(2)/(5)` x + 5 ← equation of line
