Question

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?
y = negative 2 x + 10
y = 2 x + 10
y = 10 x minus 2
y = 10 x + 2

Answer 1

y = -2x + 10
