How do I graph the equation y=-6x+1

Question

Thank You!

Answer 1

One way to graph an equation is to plot a few points on the graph.  Since this is a linear equation, its graph is a straight line, and all you need to draw a line is two points.  Pick a value of x, say 1, and plug it into the y equation to find the corresponding y value:

 

y = -6x + 1

y = -6*1 + 1         {plugged in x=1}

y = -6 + 1

y = -5

 

So one point is (1, -5)    {Remember, (1,-5) is an ordered pair: (x=1,y=-5)}

 

Pick a few other points, say x = 0 and x = 1.  Compute the y-value for each x value, and plot the points on an xy graph, then draw the line that goes through them.
