Answer:
y = -2x+4
Step-by-step explanation:
slope = (y2-y1)/(x2-x1)
= (-4-2)/(4-1)
= -6/3
= -2
point slope form
y-y1 = m(x-x1)
y-2 = -2(x-1)
distribute
y-2 =-2x +2
add 2 to each side
y-2 +2 =-2x+2+2
y = -2x+4
in slope intercept form
y = -2x+4

Answer:
8.4 km/hr.
Step-by-step explanation:
We have been given that Julia rides her horse 18 km with a constant speed of 6 km/hr.
Let us find the time taken by Julia to cover a distance of 18 km.



We are also told that she rides another 24 km with a constant speed of 12 km/hr.
Let us find the time taken by Julia to cover a distance of 24 km.



Since we know that
.
Upon substituting our values in above formula we will get,



Therefore, Julia's average speed is 8.4 km per hour.
Answer:
344
Step-by-step explanation:
Um..... sorta confusing, but I think you are only allowed to increase by 10 each time, so then you need to add 20 to make 344, where the units digit and tens digit are the same
