Hihi!
You would write it like: 2+(-3)-7 If you have any more questions be sure to ask!
I hope I helped!

To find the information you're looking for put the equation into slope intercept form: y = mx + b do this by solving the given equation for y
-7x - 4y = -20 add 7x to both sides
-4y = 7x - 20 divide both sides by -4
now you can see the slope is -(7/4) and the y intercept is 5 or (0,5)
Answer:
a) 12 (Simply divide 4800/5 to get 960. Then divide 960/80 to get 12)
b) 2100 (Simply multiply 12 by 25 by 7)
Hope it helps <3
Slope = (-7-8)/(3+4) = -15/7
We cannot determine the y-intercept unless we know at least 2 points.
Pls thank me if i am right
I hope this helped:D
