y = mx + c
as the gradient/the slope (m) is x no matter what x is 0x will always = 0
so y will alway = c the y intercept

As for example if the slope is 3 and the y intercept is 6 then the equation is: y=3x+6
If you have any expression that defines a line, you can find the slope of the line. After you have found the slope of the line, you can then write an expression describing the line in slope intercept form. You can't define a slope-intercept form for any nonlinear equation, because the slope is always* changing; there are often several intercepts as well.
Any vertical line has an undefined slope. The equation of the vertical line is x = a where the x-intercept is a.
slope-intercept from is y=mx+b, m is the slope and b is the y-intercept. put the values of the slope and y-intercept into the equation. y=2x-2
