Question

1. (03.03 MC)
The table below represents a linear function f(x) and the equation represents a function g(x):

x f(x)
−1 −11
0 −1
1 9
g(x)

g(x) = 5x + 1



Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)

Part B: Which function has the least y-intercept? Justify your answer. (4 points)

(10 points)

Answer 1

HELP PLEASE

Answer 2

Let's start with part A, the second function, g(x) = 5x + 1
By looking at function g, can you tell what its slope is?

Answer 3

THE SLOPE IS 5

Answer 4

Correct.
Now we need to find the slope of function f, so we can compare slopes.
Do you know how to find the slope of a line given 2 points on the line?

Answer 5

RISE OVER RUN SO DIVIDE THE TWO NUMBERS???

Answer 6

HELP PLEASE

Answer 7

What two numbers?
You are correct. Slope = rise/run.
We need to find the rise and the run.

Answer 8

Take any 2 points on the line.
Use any two points in the table of function f.

Answer 9

We are given 3 points on function f.
Choose any 2.
Which two do you want to use?

Answer 10

the first two

Answer 11

Ok.
The rise is the difference in y.
Rise means up or down, just like y does.
Subtract the y-coordinates of those two points.

Answer 12

so -11 - (-1)

Answer 13

Here are the first two points.
(−1, −11)
(0, −1)

We find the rise by subtracting the y-coordinates of the two points.
Rise = -11 - (-1) = -11 + 1 = -10

Answer 14

Exactly.

Answer 15

ok now what

Answer 16

i will also fan u for your help

Answer 17

The run is the difference in x.
Run means right or left, just like x does.
Subtract the x-coordinates of those two points.
The important thing here is to subtract the x-coordinates in the same order you did the y-coordinates.
