You need to find the slope of the line too. they use m to represent slope.
m   = \frac{(y2 - y1)}{x2 - x1} =  \frac{ - 2 - 2}{ - 2 - 2}  =   \frac{ - 4}{ - 4}  =  \frac{1}{1}
point slope equation is y - y1 = m(x -x1)
they said to use point (-2, -2)
y -(-2) = 1(x -(-2))
y +2 = 1(x +2)

For the diagram below, form an equation and then solve it to calculate the value of x
Talja [164]
You apply the sum of interior angles formula ie. (n-2)180. n=number of sides
since a pentagon has 5 sides it will be (5-2)180=540.
now add everything. x-5+x-6+2x-7+x+2x-2=540.
Solve for x: 7x-20=540
7x=540+20
7x=560
x=560/7
x=80

Answer:

A

Step-by-step explanation:

f(x) = 2x^2 – 3x + 1 is a function (its graph is a parabola that opens up), and it is one-to-one (Answer A).  For each input, x, this function will return one output.
