Question

HELP, medal will be given

Answer 1

the smaller triangle has a slope of -1 since you go down 4 and over to the right 4, so

m = (rise)/(run) = -4/4 = -1

Answer 2

the larger triangle also has a slope of -1

this time we're going down 6 and over to the right 6

m = (rise)/(run) = -6/6 = -1

Answer 3

since the rise/run for the two lines is the same, this means they both have the same slope of -1

and because the two slopes are equal, the two lines are parallel

Answer 4

all making sense now?
