Let x = 0 then the equation becomes y = -1.
Mark the point (0, -1) on the graph.
Let y = 0 then the equation becomes 0 = 4x-1 so that 4x = 1 or x = 0.25.
Mark the point (0.25, 0) on the graph.
Join the above two points and extend the line in both directions.
Done!
Quadrants I, III and IV.
The slope of both lines is 8. So they're parallel.
This is the equation of a line in which the slope is 1 and the y-intercept is -4.
No, not if the y is squared. When graphed the equation will not form a straight line.
