Question

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. Question Resources

Answer 1

B!

The equation x-4y= -4 is the graph, right? So that means when x is, lets say, 2, then:

2-4y= -4

Simplify
-4y=-6
y=3/2

Now if you think about it, if you plug in any number for x and get some value of y, that is the point on the graph at that x value.

Hope this helps!
