Write the equation for a linear function.
y=mx+b
Identify the slope and the y-intercept of the graph.
y-intercept: 5
slope: -2/3
List the values that represent the range of functions 
4,3,2,1,0
The y-values
Find the slope of the graph. 
2/1 = 2
In y = -3x + 2 write the slope and y-intercept.
slope = -3/1
Write the equation for the function below.

y = -2x + 6
Sketch the graph of the linear equation.
y = 4x -5
Write the domain of the table in words.
Time (s)
Find the slope from the table. 
6/1 = 6
Find the slope for the points (0,0) and (4, 6).
slope = (6-0)/(4-0) = 6/4= 3/2= 1.5
Write the equation for the graph. 
Y = 0x + 2
Y = 2
Solve the equation for y = mx + b:
2x + y = 5
y = -2x + 5
Write a sentence about what is happening in the graph between 0 and 8 hours.
As the hours increase, so does the temperature.
Find the slope of the graph. 
-1/2 = -0.5
Find the slope and y-intercept between (9, 5) and (1, -4).
slope= (-4 - 5)/ (1-9) = -9/-8 = 8/9
-4 = (8/9)(1) + b
(-4)(9/8) = b
-9/2 = b
Find the equation of a line through these points (4, 10) and ( 2, 5).
slope: (10-5)/(4-2) = 5/2
5 = (5/2)(2) + b
5= 5 + b
0 = b
y = (5/2)x + 0 OR y = (5/2)x
Solve the equation for a linear function:
3(x + (1/3)y) = 4
y = -3x +4
Write the range of the graph in words.
Temperature
Find the slope in the table of values.

3/1 = 3
Find the slope and y-intercept through
(-3, -5) and (-6, 10).
slope= (10- (-5))/(-6 - (-3)) = 15/(-3) = -5
10 = (-5)(-6) + b
10 = 30 + b
-20 = b
Find the equation for the line through (-2, -8) and (-1.5, -6).
slope= (-6 - (-8))/(-1.5-(-2)) = 2/0.5 = 4
-8 = 4(-2) +b
-8 = -8 + b
0 = b
y = 4x
Solve the equation for slope-intercept form:
0.5x - y = x + 5
-y = 0.5x + 5
Answer: y = -0.5x - 5
