Review of Slope & Intercept Flashcards

1

For the line: y = -4/3x - 7

The slope is -7
The slope is -4
The slope is -3/4
The slope is -4/3

2

when using slope how do you graph it?

rise/run
A and B
run/rise
Just keep on running!

3

what is slope?

The change in x over the change in y.
y=mx+b
run/rise
the change in y over the change in x

4

In y=mx+b what is the y-intercept?

y
mx
all of the above
b

5

Identify the slope and y-intercept for: y=-x+2

m=-1 b=2
m=0 b=2
m=1 b=2
m=2 b=0

6

What is the slope of y=-10x+2

-10

8

For: y=7

there is no slope
there is no line
the slope is undefined
this is a trick!

9

What is the slope of a the line containing points: (1,5) & (9,3)?

4
1/4
-1/4
-4

10

y=3x+10 has a y-intercept of 10, what is another way to write the y-intercept?

(10,0)
(3,10)
none of the above
(0,10)

11

In y=mx+b what is the slope?

b
m
all of the above
y

12

what is the y-intercept of y=6-2x

2
0
6

13

When graphing y = -x + 5

Start at the origin, drop 1, then right 5
Start at -5, then drop 1, then left 1
Start at 5, then rise 1, then go right one
Start at 5, then drop 1, then go right 1.

14

For the line: y=4x (may be more than one answer)

It has no slope
It has a positive slope
It starts at (0,4)
It passes through the origin

15

When graphing y=5x+8

Start at 8, then rise 5 over and over
Start at 5, then rise 8, run 1
Start at the origin, then rise 5, run 8.
Start at 8, then rise 5, run 1.

16

What is the slope of a the line containing points: (5,1) & (-9,3)?

-7
