If the sum of any 2 sides is equal to or less than the third side it is Not a triangle.
So A :- we have 2+4 = 6 so its not a triangle.
also D is not a triangle because 8+3 < 12
what about B and C?
<span>the y-intercept will be

</span>the standard line equation is y = mx + b, where y is the y point, x is the x point, m is the slope, and b is the y-intercept.
to get the y intercept, we need to transform into the line equation, and caculate out b.
3x + 5y = 8
so 5y = 8 -3x
then y = <span>

- <span>

x
which means that <span>

= the y intercept.</span></span></span>
