to find the slope of BC, you divide the length of AB over the length of AC basically slope = rise/run the slope of BC is negative since it runs downhill as you move from left to right
oh ok so the length of AB would be 3 right ? and then the length of AC would be 3 to right ?
correct on both
oh ok so if i diided those both i would get 1 right ?
@jim_thompson5910 are u there ?
so the slope of BC is -1
now find the slope of EF
ok so the length of DE would be 2 and then DF would 2 as well right and when i divide them both i get 1
make that result negative since the line EF goes downhill as you read left to right slope of EF = -1
oh ok so would this be the answer ??
yes you have shown that slope of BC = slope of EF
both are negative 1
oh ok thank you so much ^-^
do u mind helping me with just two more ?
I'll help with one more
