there are 2 ways to find the y-intercept, the hard way is to set x as 0,
eg: y=-6x+4
so y=0+4 therefore the y-intercept is 4
The easy way is to use the general equation of a straight line which is y=mx+c
where m is the gradient and c is the y-intercept so if y=-6x+4
then -6 is the gradient and 4 is the y-intercept.

the equation of a straight line is y=mx+b where b is the y intercept(that is the point the curve crosses the y axis and it is gotten by setting the x=0)
there for b=4

assume x=0
-6(0) + 4 = 4
-> y-intercept = 4
simple way...

the answer is 4. y = -6x +4. the slope (m) is -6 and the y intercept is 4. Check out http://www.schoolpiggyback.com because you can get your entire assignment done by other students there..its pretty cool...goodluck : )

Presuming you meant to write
y = -6x + 4
This is a line, in the slope-intercept form
y = mx + b
m = slope
b = y-intercept
Therefore, your y-intercept is 4.

4
remember the standard form y = mx + b wherein m is slope and b is y intercept.
in your question, -6 is slope and 4 is y intercept

-6x+4=y
-4 -4
-6x=y-4
/-6 /-6 /-6
x=-y/6+2/3
