jeremy surveyed students in his class about their spending habits in the school cafeteria. He used the data to create a scatterplot. How Students Spend Money in the Cafeteria A graph has times buying lunch per week on the x-axis, and dollars spent on the y-axis. A trend line goes through points (2, 5.5) and (5, 15.25). Which is the equation of his trend line? y = 2.75 x y = 3.05 x minus 0.6 y = 3.25 x minus 1 y = 9.75 x minus 14

answer: 177/8

step-by-step explanation:

there is no answer sorry!

step-by-step explanation:

doubled

step-by-step explanation:

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
