Basically, we need to isolate y
Assuming 0 is unnecessary:
x + 19y = 38
19y = -x + 38
Assuming that 0 is necessary:
0x+19y = 38
0•x is equivalent to 0 so that cancels out x leaving us with
19y = 38
y = 38/19
y = 2
If the 0 is necessary, your answer is y = 2.
If the 0 is unnecessary, your answer is y = -(x/19)+2

Answer:
Step-by-step explanation:
The slope formula is the change in y over the change in x, or:
Where (x₁,y₁) and (x₂, y₂) are the points the line passes through.
The points given are (0,1) and (2,6). Therefore:
Substitute the values into the formula.
Solve the numerator.
Solve the denominator.
This fraction can not be simplified further, so it is our answer.
The slope of the line is 5/2
