What is the slope of the line that passes through the pairs of points (-6,8) (2'3)

$\frac{y2 - y1}{x2 - x1}$
you should get this in the formula
$\frac{8 - 3}{2 - ( - 6)}$
$\frac{5}{8}$

Find the area of the following: <br> -square whose sides are (x+1) in length

Rainbow [258]

Area of Square = Base*Height
Base=(x+1) Height=(x+1)
Therefore Area=(x+1)(x+1) or (x+1)^2
By expanding the brackets e.g. x*x is x^2 then x*1 is x and so on you get:
x^2+x+x+1 this simplfies to x^2+2x+1
Area = x^2=2x+1
Unless they have given you a value for x, this is the equation for the area of said square.
