Question

describe how the graphs of y=x and y=x-15 are related

Answer 1

a. the graphs have the same shape. the y intercept or y=x is 0, and the x intercept of the second graph is -15.
b. the graphs have the same y intercept. the second graph is steeper than y=x.
c. the 2 graphs are the same.
d. the graphs have the same shape. the y intercept of y=x is 0, and the y intercept of the second graph is -15

Answer 2

what are the slopes of each?

Answer 3

what do you mean?

Answer 4

what is the slope of y = x

Answer 5

think of it as y = 1x + 0

and compare/match with y = mx+b

Answer 6

y=x-15 is a translation of y=x. y=x-15 has the same shape as y=x but it is shifted down 15 units

Answer 7

Jared25 is correct. Both are the same shape so to speak due to the fact that the two slopes are both 1. So they are pointing in the same direction more or less. This means the two lines are parallel.

Answer 8

so would the answer be c?

Answer 9

no, jared pointed out that they are NOT the same

Answer 10

if they were the same, then you'd see the same graph done twice. That means you'd just see 1 line (because one line lies perfectly on top of the other)

Answer 11

Nope C says that that the are same. while the shape of the graph is the same the are on different spots of the graph

Answer 12

oh okay

Answer 13

im sorry i just learned this today
