The slope-intercept is most usefull
The equation for this line would be y=2x-4
This is a linear equation
y=mx+b
y=50x+400 (when x equals the number of hours played)
1000=50x+400
*first, isolate the variable (x)
-50x=-1000+400
*divide by -50 to get x by itself
x=20+8
The answer is x=28
The answer is 7.3, If you use the order of operations, When you divide 58.4 by 8 you get 7.3
