Can you function?
Is the following relation a function, and why?
{(2, 6)(4, 8)(6, 10)(3, 7)(2, 11)
No, because the x-value of 2 repeats
m < B = 27
What is the form for the equation of a line?
y = mx + b
How many solutions do parallel lines have: one solution, no solution, or infinitely many?
No solution (they never cross)
Find the value of x, 6x = -24
x = -4
State the domain of the relation: {(5, 7)(-1, 3)(4, 8)(9, 0)(-3, 6)}
D: {5, -1, 4, 9, -3}
Angles A and B are supplementary, if < A = 114 find the m < B.
m < B = 66
Identify the slope (m) in the equation: y = 1/2x - 6
m = 1/2
Angles formed INSIDE the parallel lines on OPPOSITE sides and CONGRUENT are called...
Alternate Interior Angles
Find the value of x, 4x + 1 = 33
4x + 1 = 33
4x = 32
x = 8
State the range of the relation:
{(-2, 5)(-4, 6)(0, 8)(11, -7)(3, -1)}
R: {5, 6, 8, -7, -1}
< F and < G are complements, if < F = 2x and < G = 3x, what is the value of x?
2x + 3x = 90
5x = 90
x = 18
Identify the coordinate for the y-intercept (b) in the equation: y = -3 + 5x
b = (0, -3)
Parallel lines have the same what: y-intercept, x-value, slope, or output?
Slope (never touch)
Find the value of x: 2x + 3x - 8 = 12
2x + 3x - 8 = 12
5x - 8 = 12
5x = 20
x = 4
Which function is linear:
y = x2+7; y = 3/x - 4; y = x1/2 -1, y = -2x+7
y = -2x+7
< R and < S are supplementary. If < R = 5x and < S = 10x, find the value of x.
5x + 10x = 180
15x = 180
x = 12
Find the slope (m) of the line with points (-4, 6) and (-2, 4)
m = -1
Angles formed on the same side of the transversal and are congruent are called...
Corresponding Angles
Find the value of x: 6x = 8x - 12
6x = 8x - 12
-2x = -12
x = 6
y = 2(4) + 3 so y = 11
< W and < Z are vertical angles. If < W = 2x and < Z = 100, what is the value of x?
2x = 100
x = 50
Fins the slope of the line with the points (3, 8) and (3, 2)
m = -6/0; UNDEFINED
State the slope (m) of a line which is parallel to the line y = -3/4x + 5
m = -3/4 (same slope)
Find the value of x: 5x + 6 = 3x - 8
5x + 6 = 3x - 8
2x + 6 = -8
2x = -14
x = -7
