2.3.3 quiz: linear functions

question 4 of 10

2 points

what is the slope of a line is parallel to y = (1/2)x+ 3?

what is the answer and how would i get there?

1/2

Step-by-step explanation:

The line equation is:

where m is the slope and b is the y-intercept

Parallel lines are those that have the same slopes so according to the line that you wrote we have that

any parallel line has to have the same slope, in this case it has to be 1/2

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
