Write an equation in point-slope form of the line having the given slope that contains the given point.
m=-3, (-2,1)

A. y-1=-3(x+2)
B. y-3=-2(x-1)
C. y= -3x+3
D. y+2=-3(x-1)

A

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 3 and (a, b) = (- 2, 1), thus

y - 1 = - 3(x - (- 2)), that is

y - 1 = - 3(x + 2) → A

the high of the aircraft at the time of takeoff is 33 meters

Step-by-step explanation:

height of hovercraft x second after takeoff =h(×)= -(x-11)

(x+3)

We want to know the height of the hovercraft 0 seconds after takeoff

height of hovercraft 0 seconds after takeoff=h(0)= -(0-11)

(0+3)= -(-11)(3) = 33
