Answer:In last graph y = -3 is the graph of linear equation Ax+By=C.
Explanation:
Given: Linear equation in standard form Ax+By=C , where A=0, B is positive , and C is negative .
To find : Which graph show the equation .
Solution : We have given that Ax+By = C.
Where, A = 0 , B = positive , C = negative .
Plugging A = 0 , C = negative .
0 x +By = C.
y =
.
We can see y would be negative .
Therefore , In last graph y = -3 is the graph of linear equation Ax+By=C.
