y=ax+b
b=y intercept
to find the x-intercept, get x alone on one side and plug 0 in for y
when you are trying to find gradients and intercepts in Maths. There are 3 easy ways to do this
1) Firstly, measure how much the line goes across from the y axis
2) Then measure how much it goes down(which will be a negative number) or up(which will be a positive answer).
3) Finally add the two numbers together to find the gradient then the equation should go like y=(the gradient) with x and the intercept(when it hits the y axis)

How do you work out the x and y intercepts?
Ax+By=C
Do functions always have x and y Intercepts?
the x is dependent and the y is independent and the x numbers cant repeat themself and yes they do have intercepts
What are the x-intercepts and Y-intercepts for the graph 3x plus 15 equals 5y?
X intercept: -5 Y intercept: +3
What if you cant do find the x intercepts?
Then there is no x-intercept. No big deal. Lots of functions do not have x- intercepts. For example, y = x2 + 1 or y = 2x
For which values does the cosecent functions have x intercepts?
The cosecant function, being defined as 1÷sin(x), has no x intercepts. It has y intercepts at ±∞. (infinity and -infinity)
