I need help on number 7

y=2x+2  and increasing

Step-by-step explanation:

we see there is a pint (0,2)  so the y intercept is 2, we know the slope is 2 because the slope formula can be used on ay two points, for example (0,2) and (1,4)    4-2 is 2 and 1-0 is 1.    2/1 =2 so the slope is 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

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars
