There is word form(which means write the number down, so lets just say I have the numbers 82,7,and 12. So I'll write eighty-two, seven, and twelve. There's also standard form, so lets say I have the numbers 27 and 15 I'll write 20+ 7, then 10+5.) I hope you got it! Good luck

Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
We have the slope m = -1/5. Substitute:

Put the coordinates of the given point (-3, 7) to the equation:

<em>subtract 3/5 from both sides</em>

If you find the discriminant it will tell you the number and types of roots. The discriminant is the value b^2 -4ac.
a = 1
b = 1
c = 1
1^2 - 4*1*1
1-4 = -3
Since this is a negative number there will be 2 complex roots.
Not sure right now give me a few mins
X would be the absolute value of 10 or -10 since they both are 10 units from 0 so it can be x=l10l or x=l-10l, they both equal 10
