Write out the line equation first.
y = 2/3 x + c
Since we have a pair of coordinates (6,5), we can substitute it into the line equation to find the y-intercept.
5 = 2/3 (6) + c
y-intercept, c = 1
y = 2/3x + 1
To find any 2 possible coordinate pairs, substitute x = 0 and y = 0 to find x and y intercepts.
1. sub x = 0 into the equation:
y = 1
First pair of coordinates: (0 , 1)
2. sub y = 0 into the equation:
x = -3/2
Second pair of coodinates: (-3/2 , 0)
