QUESTION
Which way does the graph of a linear function with a negative slope go as you read from left to right?
QUESTION
Starting at the y-intercept of
y
=
3
4
x
+
1
y = \frac{3}{4}x + 1
y
=
4
3
x
+
1
, you move 4 units right. How many units up do you move to stay on the line?
QUESTION
What is the x-intercept of the graph of
y
=
2
x
−
6
y = 2x - 6
y
=
2
x
−
6
?

(3, 0)
(
3
,
0
)
. Setting
y
=
0
y = 0
y
=
0
gives
2
x
=
6
2x = 6
2
x
=
6
, so
x
=
3
x = 3
x
=
3
