Is the slope positive or negative?
Positive
100
Slope= 4 and y-intercept= -2
y= 4x - 2
100
y = 2x + 1
100
2y= 10x - 8
y= 5x -4

200
y = 1x + 1
200
y= -2/3x + 4
200
2x + y= 4
y= -2x + 4

Is the following a function?
Yes b/c it passes the VLT
300
Find the slope
-2/3
300
(-4, -7); slope = 1
y= 1x -3
300
y= 1 - 5/6x
300
x - y= -3
y= x + 3
300
Solve for x.
3(x - 4)= 2(-2x +1)
x= 2

400
(1,6) and (2, 5)
y= -x + 7
400
2x - 4y = 20
400
-6x + 4y= 20
y= 3/2x + 5
