Math helpppp!! please help

1. What is the slope of the line that passes through (8, 4) and (6, 7)?

a
-3/2

b
3/2

c
-2/3

d
2/3



2. If y varies directly with x, and y = 2 when x = 6. Find y when x = 3/4.

a
1/3
b
1/4
c
Not Enough Information
d
1/2



3. Which of the following pairs of coordinates are on a line with an undefined slope?

a

(2, 1), (5, -2)

b

(3, -2), (3, 5)

c

(-2, -2), (4, 4)

d

(-4, -3), (3, -3)

4. In the relation {(0, 2), (-1, -3), (9, 7), (4, -3)}, the range is {0, -1, 9, 4}.
True
False



5. Find the equation of the line through (1, -5) with slope -2.

a
y = -2x + 3
b
y = -2x - 3
c
y = 2x - 3
d
y = 2x + 3

y2-y1/x2-x1 = -3/2

y=2 x=6 y=(1/3)x ----> 1/3 * 3/4 = 1/4

(3, idgaf) (3, idgaf) because 3-3 makes it undefined

y=-2x+3
