Associative Property of Multiplication
If f(x) = 2x + 1, find f(-4)
f(-4) = 2(-4) + 1
f(-4) = -8 + 1
f(-4) = -7
Write the following equation in slope-intercept form: 5(x + 2y) = 20
y = -1/2x + 2
What is the slope of the following equation:
2x + 2y = 8

Evaluate:
[(2*3)+(7*4)]+2
Algebra: 36
Solve for y:
3x + 8y = 16
y = -3/8x + 2
This is the equation that goes through (3,8) and has a slope of -5
y-8 = -5(x - 3)
OR
y= -5x + 23
Solve: 21 + x = 2(x - 6)
x = 33
