Answer:
a = 2
b = 3
Step-by-step explanation:
Since they both are points on the line they'll both satisfy the line equation, and we can substitute their x-coordinate and y-coordinate into the equation, then solve the system of equations we obtained:
3a = 6
-3a + 4y = 6
From the first one we find that a = 2. Let's substitute in the second:
-3*2 + 4y = 6
y = 3
