Simple Equations
Solve: (3 - 3x)/7 = 6
x = -13
Simplify: 3(x-4)+2x
5x-12
Solve: 3x + 4 = 7
x = 1
What is the slope of the following equation:
2x + 2y = 8
slope = -1
is 555,098,784,832 divisible by 8? explain
yes, b/c 832 is divisible by 8
A line with a slope of 6 passes through the point (2,6). What is its equation in point-slope form?
y-y1 = m( x- x1)
y-6 = 6 (x-2)
Evaluate: 2(j–12.3)–7.6 = 4.8
j =18.5
The points (9,3) and (4,4) fall on a particular line. What is its equation in point-slope form?
y-3 = -1/5 (x-9)
or
y-4 = -1/5 (x-4)
Solve: 21 = (x/3) - 12
x = 11
What's the slope of the line passing through (3,9) (5,4)
slope: -5/2
