Leon correctly found the slope and y-intercept of the line that passes through the points (9, –8) and (3, 4) as follows.
m = StartFraction negative 8 minus 4 Over 9 minus 3 EndFraction = StartFraction negative 12 Over 6 EndFraction = negative 2. y = negative 2 x + b. Negative 8 = negative 2 (9) + b. Negative 8 = negative 18 + b. 10 = b.
What is the equation of the line in slope-intercept form?
