Answer:
(0, 12 )
Step-by-step 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 =
with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (- 5, - 3)
m = =
= 3 , then
y = 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 3, 3 ), then
3 = - 9 + c ⇒ c = 3 + 9 = 12 ← y- intercept
Thus the line crosses the y- axis at (0, 12 )
