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 $1$.)
(-4,0) and (0,2) are on the line
Slope = [ 2 - 0 ] / [ 0 - - 4] = 2/ 4 =1/2
Equation
y = (1/2)x + 2 multiply through by 2
2y = x + 4
x - 2y = -4
+2653
