Question

Help plzzzz !! thanks

Answer 1

C

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 ) = 2, 3) and (x₂, y₂ ) = (0, - 1)

m =
`(-1-3)/(0-2)` =
`(-4)/(-2)` = 2

The line crosses the y- axis at (0, - 1 ) ⇒ c = - 1

y = 2x - 1 → C
