Given the equation, y=3x - 7 what is the slope of the line?

3

Step-by-step explanation:

y = mx+b

m = slope

y=3x - 7

m = 3 =slope

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y = mx + b

m - slope

b - y-intercept

We have the equation y = 3x - 7.

Therefore

the slope m = 3

the y-intercept = -7

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
