## Algebra 1

The relationship is a function because it passes the vertical line test which states that each x-value has one y-value Equation: Slope: $\frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}$ $\frac{(8-5)}{(1-0)}$ $\frac{(3)}{(1)}$ slope=3 y-int: y=3x+b (substitute any x & y value from the table) 5=3(0)+b 5=0+b 5=b Equation: y=3x+5
