Try using a slope-intercept equation.
y = mx + b
Use the slope and y-intercept to make the equation.
y = 3x + 2
Substitute 1, 2, 3, and 4 for n to find the terms.
t(1) = 3 –1 t(2) = 6 –1 t(3) = 9 –1 t(4) = 12 – 1
Graph the results.
t(1) = 2 t(2) = 5 t(3) = 8 t(4) = 11
Notice that both graphs have the same slope.
The graphs are parallel, but they have different intercepts. The first is continuous and the second is discrete.
