Question

y–4x+1=0

Answer 1

geez - how many times do you have to post the same lame question?
And not even say what it is you want to know?

Answer 2

This is a linear equation in two variables (y and x) that represents a straight line. To graph it, we can solve for y and plot points or use intercepts:

y = 4x - 1

To find the x-intercept, set y to zero and solve for x:

0 = 4x - 1
4x = 1
x = 1/4

So the x-intercept is (1/4, 0).

To find the y-intercept, set x to zero and solve for y:

y - 4(0) + 1 = 0
y = -1

So the y-intercept is (0, -1).

Plot these two points and draw a straight line passing through them.
