+1791 How do you solve lines
Find the equation whose graph is shown below. Write your answer in standard form.
(Standard form is $Ax+By = C$, where $A$ is positive, and $A$, $B$, and $C$ are integers with greatest common divisor $1$.)
+36916 Pick any two points on the line to calculate the slope = rise/run = 1/2
then y = 1/2 x + b sub in any point to calculate the value of 'b'
2 = 1/2(0) + b shows b = 2
y = 1/2 x + 2 re-arrange
1/2 x - y = -2 multip;ly through by 2 ( to get rid of the fraction)
x - 2y = -4
