48 = 2x - 8y 8y = 2x + 48 y = (2x + 48)/8 y = 1/4x + 6
Answer : 1/4
G e n er a l e q u a t i o n f or l in e in s l o p e in t erce pt f or m : y = a x + b a − s l o p e − 48 = 2 x − 8 y ∣ a dd 8 y 8 y − 48 = 2 x ∣ a dd 48 8 y = 2 x + 48 ∣ d i v i d e b y 8 y = 4 1 x + 6 Sl o p e i s e q u a l t o a = 4 1 .
The slope of the line from the equation − 48 = 2 x − 8 y is − 4 1 . This was determined by rearranging the equation into the slope-intercept form. In that form, the coefficient of x gives the slope directly.
