Pre-Image
How many solutions does the equation have?
3x + 6 - 2x = x + 8
No solution
Determine if the relation is a function or not. Explain.
(1, 2) (3, 4) (5, 6) (7, 8)
Yes, there are no repeating input values.
Explain how you would graph the equation:
y = 3x - 5
Make a point at -5 on the y axis. From that point, rise up 3 and run right 1 and make another point.
Will these angles create a triangle?
90 degrees, 80 degrees, 25 degrees
Explain.
No, they do not add up to 180 degrees
