Answer:
Linear equation is 
Step-by-step explanation:
We have,
Total monthly income (in dollars) = y
Number of times an app is opened = x
As, the advertiser pays $0.002 each time an app is opened.
So, the amount paid by the advertiser if an app is opened x times = 0.002x dollars.
Since, $30 per month is also paid by the advertiser.
Thus, total monthly income 'y' is given by,
Hence, the graph of the linear equation is given below.
To find the slope of a line given the coordinates of two points, you should use the formula, Slope=y2-y1/x2-x1.
To find the slope of a line which contains the coordinates (8,-3) and (-2,7), you should substitute them into the previous mention formula.
Slope=y2-y1/x2-x1
Slope=(7--3)/(-2-8)
Slope=(10)/(-10)
Slope=-1
The slope of the line which contains the coordinates (8,-3) and (-2,7) is -1 or in other words letter A from the given choices.
the square root of 25 is 5 i hope this helped and enjoy your day!
Answer:
Step-by-step explanation:
x - 2y = 8
Write this in y = mx +b form
- 2y = -x + 8
Divide the equation by (-2)
Slope = 1/2
The slope of the perpendicular line = -1/m
m = -2 , ( -2 , 5)
Equation: y = mx +b
Plug in m = -2 ,x = -2 and y =5
5 = (-2)*(-2) + b
5 = 4 + b
5 - 4 = b
b = 1
Equation of the line:
y = mx +b
y = -2x + 1
