I need help with graphing its not a graded quiz

Keewee, this is the solution:
Step 1: Let's find two coordinate points to calculate the equation:
(0, 5)
(6, 3)
Step 2: Let's calculate the slope, as follows:
m = 3 - 5/6 - 0
m = -2/6
m = -1/3
Step 3: Let's calculate the y-intercept, using (6,3):
y = mx + b
3 = -1/3 * 6 + b
3 = -2 + b
b = 5
Step 4: Finally, we can write the equation:
y = -1/3x + 5
