On a whiteboard, graph y=1/2x with the domain 0,2,4,6,8
Teacher checks for the following ordered pairs (0,0)(2,1)(4,2)(6,3)(8,4)
200
Solve the proportion. Check your solution. 11/6 = x/30.
x = 55
200
Tell whether (4, -1/2) is a solution of x + 2y =5. (Show your work)
not a solution
200
Write an equation for a linear function f that has the given values: f(-4)= -8, f(-8) = -11
y = 3/4x - 5
200
Rewrite the equation in slope-intercept form. Then, Identify the slope and y-intercept of the line. 6x -3y = -9.
y = 2x + 3; m =2, b = 3
300

For every input, there is only one output.
300
Solve the equation. Check your solution. 4/3(7 - n)=12
n = -2
300
On whiteboards, graph the function y = -3x + 1 with the domain x<0. Then identify the range of the function.
Teacher check graphs; range y>1
300
Write an equation in point-slope form of the line that passes through the given points: (-3, 20) (4, 36)
y + 20 = 8(x + 3) or y - 36 = 8(x - 4)
300
On whiteboards, graph using slope-intercept form: y = 3x + 4
Teacher check whiteboards.
400

Write an equation in standard form of the line that passes through the given point and has the slope m. m = 1/6; (-6, -10)
x - 6y = 54
400
For the function f(x) = 2x - 10, find the value of x so that f(x) = 6.
x = 8
