Switch y and x to find the inverse:
x = 3y - 8
Now just solve for y
y = x/3 + 8/3
Answer:
y = 0 and x = 6
y = 2 and x = 3
y = 4 and x = 0
y = 6 and x = -3
Step-by-step explanation:
2x+3y=12 is the equation of a straight line.
There are infinite number of solutions, but here you're probably looking for solutions where x and y are whole numbers. Trial and error will find you some, although if you examine the equation closely you see that if x is a multiple of 3 and y is a multiple of 2, then they produce terms that are the LCM (least common multiple) of 2 and 3, namely 6. That's the logic in the whole number solutions.
lines with undefined slope are vertical
equation are in form of x constant
through the points ( 3 , -4)
the line is x=3
Answer:
-25
Step-by-step explanation:
-81=7k+19=3k
7k-3k=-19-81
4k=-100
k=-25
