Question

@satellite73 How do I do this one?

Which linear function has a greater rate of change?
Function A:
x -1 0 2 3
y 3 -1 -9 -13

Function B: y = -4x + 10
A. Function A, because 3 > -4.
B. Function B, because 10 > -13.
C. Function B, because 10 > -4.
D. The functions have the same rate of change.

Answer 1

the rate of change of \(y=-4x+10\), i.e. the slope, is \(4\)

Answer 2

you need to be able to compute the rate of change (slope) for the other one
do you know how to do that?

Answer 3

No.

Answer 4

ok first we do it in our heads, then we use a formula

Answer 5

x -1 0 2 3
y 3 -1 -9 -13
this means when \(x=-1\) we have \(y=3\) and when \(x=0\) we have \(y=-1\)
from \(-1\) to \(0\) is one step right in the \(x\) direction, from \(3\) to \(-1\) is four steps DOWN in the \(y\) direction
right 1, down 4, rate of change is \(-4\)

Answer 6

A or C?

Answer 7

guess i was not clear
the rate of change of your table is \(-4\) and the rate of change of \(y=-4x+10\) is also \(-4\)

Answer 8

Oh! D?

Answer 9

lol right
