Answer 1

do you know y = mx + b?

Answer 2

yeah

Answer 3

do you know how to figure out the value of m from the graph?

Answer 4

yes, i did that and I got m = -1

Answer 5

and what is b?

Answer 6

so i figured, answer would be -x because there was no b

Answer 7

Hm. i1 is the slope of the line. This graph actually makes it easy because what does b stand for in y = mx + b?

Answer 8

in words

Answer 9

y intercept

Answer 10
