Question

Can someone help me what is the answer

Answer 1

y = 4x + 3

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 ) = (- 1, - 1) and (x₂, y₂ ) = (0, 3)

m =
`(3+1)/(0+1)` =
`(4)/(1)` = 4

The line crosses the y- axis at (0, 3 ) ⇒ c = 3

y = 4x + 3 ← equation of line
