basically I learned this trick at school, you take the percent, in this case it’s 95/100 and then you write it next to the fraction of what your unit is, so x/20 students
then you multiply 95 and 20 then divide by 100.
5: 5, 10, 15, 20, 25, 30, 35, 40
10: 10, 20, 30, 40
least common multiple is 10

Answer:
y = -x -12
Step-by-step explanation:
The slope of the line you want is the same as the slope of the line you have: -1. Then the point-slope equation of the line is ...
y -k = m(x -h) . . . . . . line of slope m through point (h, k)
y -(-7) = -1(x -(-5))
y = -x -5 -7 . . . . subtract 7, eliminate parentheses
y = -x -12 . . . slope-intercept equation
