TABLE OF VALUES:
x|y
1|3
2|6
3|13
4|22
5|46
to find what is the equation used to find y=ax%2Bb, use any two given points and find the equation of line going through that points

Solved by pluggable solver: Find the equation of line going through points
hahaWe are trying to find equation of form y=ax+b, where a is slope, and b is intercept, which passes through points (x1, y1) = (1, 3) and (x2, y2) = (4, 22).
Slope a is .
Intercept is found from equation a%2Ax%5B1%5D%2Bb+=+y%5B1%5D, or 6.33333333333333%2A1+%2Bb+=+-3.33333333333333. From that,
intercept b is b=y%5B1%5D-a%2Ax%5B1%5D, or b=3-6.33333333333333%2A1+=+-3.33333333333333.

y=(6.33333333333333)x + (-3.33333333333333)

Your graph:





or, you can write it as
y=%2819%2F3%29x+-10%2F3
