A line passes through the points (1, –6) and (4, 3). A coordinate plane. What is the y-intercept of this line? –9 –3 3 9

-9

Step-by-step explanation:

eq.of line is

y+6=(3+6)/(4-1) ×(x-1)

y+6=3(x-1)

y+6=3x-3

y=3x-3-6

y=3x-9

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

10cm
