| 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) = (2, 3) and (x2, y2) = (1, 5).
Slope a is  .
Intercept is found from equation  , or  . From that,
intercept b is  , or  .
y=(-2)x + (7)
Your graph:
