Find and equation for the table below?
:
One definition of slope is rise over run
S 1 2 3 4 5 6
T 1 4 7 10 13 16
:
You can see that for a run of 1, we have rise of 3, therefore
slope (m) = or just 3
:
Use the point/slope formula: y - y1 = m(x - x1)
Using the 1st point: 1,1
y - 1 = 3(x - 1)
y - 1 = 3x - 3
y = 3x - 3 + 1
y = 3x - 2
:
Substitute S for x and you will get T
