Question 1122732: I have to solve an input output problem
12-16
16-19
20-22
24-25
26-26.5
And I don’t know how to express their relationship, I know it’s +4, then +3, +2,+1,+0.5

| 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) = (12, 16) and (x2, y2) = (24, 25).
Slope a is  .
Intercept is found from equation  , or  . From that,
intercept b is  , or  .
y=(0.75)x + (7)
