What do you mean? just the number 80?
<span>4x+2y=-6
2y = -4x - 6
y = - 2x - 3
slope = -2
</span><span>y-intercept when x = 0
so y = -3
answer
slope = -2
</span><span>y-intercept (0,-3)</span>
This is already written in scientific notation, but if you are asking what the answer would be written out it is: 400000
