Use the information given to enter an equation in standard form.
Marysya12 [62]

Answer:

The equation in the standard form of the line through the given points is;

y = 3x - 17

Step-by-step explanation:

We start by getting the slope of the line;

m = (y2-y1)/(x2-x1)

m = (7-10)/(8-9) = -3/-1 = 3

The stands equation form is;

y = mx + b

m is slope, b is the y-intercept

so we have

y = 3x + b

To get b, we substitute the coordinates of any of the points

10 = 3(9) + b

10 = 27 + b

b = 10-27

b = -17

So the equation is;

y = 3x - 17

Change 240 to radian measure in terms of pi
Vera_Pavlovna [14]
To change a degree measure to a radian measure, we multiply by (π/180). So 360° becomes 2π radians, and 240° becomes 4π/3.

HELP PLS
Neko [114]
Expansions and compressions are transformations that change the length or width of the graph of a function.


 To graph y = a*f (x)
 if a> 1, the graph of y = f (x) is expanded vertically by a factor a. 
 We have then:
 f (x) = 2/5 x ^ 2-2
 The function g (x) is a vertical stretch of f (x) by a factor of 2:
 g (x) = 2f (x)
 g (x) = 2 (2/5 x ^ 2-2)
 g (x) = 4/5 x ^ 2-4

 Answer:
 The equation of g (x) is: 
 g (x) = 4/5 x ^ 2-4
