And best gets brainliest.
school is 2 miles from home along a straight road. the table shows your distance from home as you walk home at a constant rate.

time(mins): 10-20-30
distnce(mi)1.5-1-0.5

1)is the relationship in the table
proportional?
2)find your distance from school fro each time in the table
3)write an equation representing the relationship between the distance from school and time walking.

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough

the graph line crosses the x axis at both -6 and -2, so the answer would be the second one.
