Answer:
y = - 3x - 1
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 ) = (- 1, 2) and (x₂, y₂ ) = (0, - 1)
m = = = = - 3
the line crosses the y- axis at (0, - 1 ) ⇒ c = - 1
y = - 3x - 1 ← equation of line
Answer:
x = (4r +3)/(r +2)
Step-by-step explanation:
Collect x terms, then divide by the coefficient of x.
x(r +2) = 4r +3
x = (4r +3)/(r +2)
