do you mean:
3x-7y=8 1. you have to get this equation set to "y=" form, so add
7y to both sides.
3x=7y+8 2. now subtract 8 on both sides
7y=3x-8 3. get "y" by itself, by dividing by 7 on both sides.
y=3/7x -8/7 4. now find your "y intercept" formula y=Mx+B, "B" equals
your "y intercept."
-8/7 5. answer
You state that y + x = -8 The y intercept is where x = 0 so replace that in the formula: y + 0 = -8 So the y intercept is at -8 ... (0, -8) is the point you're looking for.
The slope intercept form is y=mx+b where m is the slope and b is the y intercept y=2x-8.
y = slope*x + intercept, so y = -8x + 5
If: y = 8x+7 then the y intercept is 7 and the slope is 8

You state that y + x = -8 The y intercept is where x = 0 so replace that in the formula: y + 0 = -8 So the y intercept is at -8 ... (0, -8) is the point you're looking for.
If you mean: y = 3.5x+8 then the slope is 3.5 and the y intercept is 8
Add 8 to the x value, so f.e. If x=4, the y intercept = 4+8 =12 No, the y intercept is the value of y when the value of x = 0, so the y intercept of the equation is 8. In the general form y = mx + b, b will always be the y intercept.
The slope intercept form is y=mx+b where m is the slope and b is the y intercept y=2x-8.

8
Set y = 0 -x = 8 so that x = -8 is the x-intercept. Set x = 0 2y = 8 so that y = 4 is the y-intercept.
y = slope*x + intercept, so y = -8x + 5
-6
It is 8
