Question

Can someone help fan + medal
State whether every point on the graph is a solution of the equation. Explain why or why not.
x – 4y = –4


A.
Every point shown on the graph is not a solution of the equation because when the coordinates of the points are substituted into the equation, the equation is not true for all the points.







B.
Every point shown on the graph is a solution of the equation because when the coordinates of the points are substituted into the equation, the equation is true for all the points.

Answer 1

You need to transfer x-4y=-4 into traditional linear form like y=mx+c or/and put the values of coordinates into the expression
1. (-4,0) -4-4*0=-4, so -4 is equal to -4
2. (0,1) 0-4*1=-4, so -4 is equal to -4
3. (3,2) 3-4*2=-5, so -5 is not equal to -4
