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 $1$.)
The points (-4,0) and (0,2) are on the graph
Slope = (2 - 0) / ( 0 - - 4 ) = 2/4 = 1/2
Using (0,2) we can write the equation ofthe line as
y = (1/2)x + 2 multiply throygh by 2
2y = x + 4
x - 2y = -4
