You marked off your shop floor in a grid of 1 foot squares and Labeled them with Cartesian coordinates. To perform one task a worker must go from point (2,7) to point (10,6) then back to point (2,7). The worker walks in a straight line between points. How far does she have to walk?

.25

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

d. corresponding side lengths in similar triangles are proportional in length.
