Answer:
It’s y = 3
Step-by-step explanation:
Solve for y by simplifying both sides of the equation, then isolating the variable.
Slope is rise/run or y2-y1/x2-x1. So to find the slope, find two points where the point is exact, then do the equation. That's the best I can explain, sorry if this doesn't help at all.
In order to answer this question let's suppose,
Joe is x miles from the beginning and y miles from the end. These assumptions are necessary to answer further:
Now,
x=2y
x+y=30
plugging in x=2y in the above equation
2y+y=30
3y=30
y=10
Hence, according to our calculations, Joe has to hike 10 miles further
Slope is equal to the change in y over change in x, or rose over run m= 1/3
