Which of the following is an equation of the line with slope 2 that passes through the point (-1,-4)

y = 2x - 2

Step-by-step explanation:

Step 1:

y = mx + b        Slope Intercept Form

Step 2:

y = 2x + b     Substitute Slope

Step 3:

- 4 = 2 ( - 1 ) + b     Substitute x and y

Step 4:

- 4 = - 2 + b     Multiply

Step 4:

- 2 = b      Add 2 on both sides

y = 2x - 2

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

50-38=12
