Write in slope-intercept from an equation of the line that passes through the given points (-9,9), (-3,7)

Answer:
y = (-1/3) x + 6
Step-by-step explanation:
y = mx + b m: slope b: y interception
m = (y-y') / (x-x') = (7-9) / (-3 - (-9)) = -2 /6 = - 1/3
for (-9,9) b = y - mx =9 - (-1/3) ×(-9) = 6
y = (-1/3) x + 6
check: for (-3,7) 7 = (-1/3) × (-3) +6
