A line passes through the points (-3,-5) and (8,1). The equation of this line can be expressed in the form Ax+By=C, where A,B , and C are integers with greatest common divisor and is positive. Find A+B+C
+367 In order to find the equation, you need to find two things. The y intercept, and the slope. Let's start with slope.
Slope is y/x, so 1-(-5)/8-(-3) = 6/11
This means -A/B = 6/11 (I think some part of the copy and paste didn't show up for the "is positive" part)
This means A and B equal -6,11 or 6,-11
Now for C, We can use one of the coordinates given. Let's use (8,1). -48 + 11 = C, C = -37. Note that if we used the other A and B, C would be 37.
Hope that helped :)
