How do you graph the equation for Y plus 4x equals 1?

Answer 1

Choose sensible scales for the X and Y axes.

Then plot two points for chosen values of x, say x = 0 and 5, the y values being calculated form the equation:

x = 0 → y = 4 x 0 + 1 = 1

x = 5 → y = 4 x 5 + 1 = 21

Finally, as y = 4x + 1 is a linear equation, draw a straight line through those two plotted points (0, 1) and (5, 21).
