Fun with Equations
Algebra: Is this a function: {(1, 2), (2, 3), (2, 4)}
Algebra: No
(x,y)
What are the two different ways you can graph a positive slope?
Up and to the right or down and to the left
evaluate: 3 + -2 * 5
-7
Which is not true?
7 + x = x + 7
4*(x+3)=(x+3)*4
x-2=2-x
x-2=2-x is not true
What is the slope intercept form of a linear equation:
y = mx + b
What are two different ways you can graph a negative slope?
Down and to the right or up and to the left
Algebra: Solve for a: ax + b = c
Algebra: a = (c - b)/x
Solve: 2(2x-4)=32
x = 10
Evaluate: {[(2 * 3) + (7 * 4)] + 2} * [(8 - 6) - (4 - 3)]
Algebra: 36
Simplify: a(b - c) - 2a(c + b)
-1ab - 3ac
Simplify: -4(3x - 2) -2(4 + 3x)
-18x
Evaluate 1/4 + 2/9
17/36
simplify: 3(x-4)-2(3x-1)
-3x-10
What's the slope of the line passing through (3,9) (5,4)
-5/2
Solve the following system of equations by substitution
y=2x 3x+2y=21
