write an equation of a line given (x1,y1)=(12,7) and (x2,y2)=(-4,5)

Now use

That will do as a final answer if you only want the slope-intercept
form, or,
you can multiply through by 8 and get rid of fractions

and to get it in standard form Ax + By = C

and since the standard form requires that A be positive,
we multiply thru by -1

Solved by pluggable solver: FIND EQUATION of straight line given 2 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, 7) and (x2, y2) = (-4, 5).
Slope a is .
Intercept is found from equation , or . From that,
intercept b is , or .

y=(0.125)x + (5.5)
