The line with equation crosses the y-axis at (0, 0), so the y-intercept is 0. While the line with equation x = 1 does not cross the y-axis at all (it is parallel to it), so it has no y-intercept.
The coordinates of the x intercept for the equation y equals x plus 1 is (x=-1, y=0).
y = mx + b <-- (Slope Intercept equation) y = 4x - 1 <-- (Slope Intercept form)

If the equation is: y = -x then the slope is -1 and there is no y intercept
The coordinates of the x intercept for the equation y equals x plus 1 is (x=-1, y=0).

that is an equation of a line with a slope of 1 and y-intercept of -3 and x-intercept of 3
-1
If the equation is: y = -x then the slope is -1 and there is no y intercept
The easiest way to find the y intercept for that line is to divide both sides by 2 We now have the equation y=5/2 x-1 which tell us the y intercept is -1. Another way is to understand that at y intercept, x equals zero this implies equation becomes 2y=(-2). Divide both side by 2 it gives y=(-1) which is the y intercept.
The equation y=6x+1 is in "slope intercept" form. This form is y=mx+b and b is the y intercept and m is the slope. This means we can read the slope and the intercept directly from the equation with no calculations. The slope is 6 and the y intercept is 1 ( or the point (0,1) is you prefer)
The y-intercept for the equation y=-7x+1 is (0,1). When x=0, y= -7*0+1 = 1
