What is the slope of a trend line that passes through the points (5, 80) and (7, 65)?
Sedaia [141]

The slope of a trend line that passes through the points (5, 80) and (7, 65) is -7.5.

Step-by-step explanation:

If the line is passing through two points (x1, y1) and (X2, y2). The slope (m) can be calculated using following formula.

m = \frac{y2-y1}{x2-x1}

In this case,

x1  = 5

x2 = 7

y1  = 80

y2 =  65

By putting the values in formula, we get

m = \frac{(65-80)}{7-5}

m = \frac{(-15)}{2}

or

m = -7.5

Therefore, the slope of a trend line that passes through the points (5, 80) and (7, 65) is -7.5.

Solve x^2 - x = 2 using the quadratic formula. Show your work.
lesya [120]
The quadratic formula is the result of completing the square for ax^2+bx+c=0 when a,b, and c are unknown values.  This result is:

x=(-b±√(b^2-4ac))/(2a), we have x^2-x-2=0 so

x=(1±√(1+8))/2

x=(1±√9)/2

x=(1±3)/2

x=-1 and 2
