Y = mx + b
slope(m) = -1
(7,2)...x = 7 and y = 2
now we sub and find b, the y int
2 = -1(7) + b
2 = -7 + b
2 + 7 = b
9 = b
so ur equation of this line is : y = -1x + 9.....can also be written as :
y = -x + 9....or if u need it in standard form, it is : x + y = 9
Sum means add
sum of the 3 is
n+n+1+n+2
it add to 57
n+n+1+n+2=57
3n+3=57
minus 3 both sides
3n=54
divide both sides by 3
n=15
n+1=16
n+2=17
the integers are 15,16, and 17
<span>10q + 5 = 5q + 5q + 5

Independent variables (IV): These are the factors or conditions that you manipulate in an experiment.
Dependent variable It is something that depends on other factors
A constant is a value or number that never changes in expression; it's constantly the same.
A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results.
