Question

I need step by step explanation of this question ​

Answer 1

Solution: Remember that you can represent an equation as a table and as a graph.
I would start by build a table of ordered pair that make the equation true.
For example, When x is 0, y is -4*0 = 0. So, the ordered pair (0,0) is part of the graph. When x is 1, y is -4*1 = -4. So, the ordered pair (1, -4) is part of the graph. When x is -2, y is -4*-2 = 8. So the ordered pair (-2, 8) is part of the graph. Now we have a table that looks like this
the table is attached
You can keep going like this for as long as you want, but usually 3 of 4 points will give you a sense of what's going on. Now we graph those points on an x-y coordinate grid.

We see that these points are part of a straight line. We can connect the dots. Every ordered pair on the line makes the equation y=-4x TRUE. Every ordered pair off that line makes the equation FALSE.
