Gradient= -2
Y intercept= 1
Answer: y= -2x + 1
78, 130, and 91. You're welcome :D
Answer:
x-intercepts: (2,0)
y-intercepts: (0,3)
Step-by-step explanation:
Answer:
1 / 2 or 0.5
Step-by-step explanation:
use the formula ; m = y2 - y1 / x2 - x1
where y2 = 10
y1 = 9
x2 = 5
x1 = 3
Answer:

Step-by-step explanation:
Because the function is symmetric about the y-axis, using the cosine function is most appropriate.
<u>Refer to the equation for a cosine function:</u>
<u />
<u />
Amplitude: 
Period: 
Phase shift: 
Midline: 
The amplitude would be the average of the maximum and minimum y-values of the function, which would be
.
The value of
in
represents the length of the period, so since the length of the period is
, this means that
.
The phase shift,
, describes the horizontal shift of a function. Because the phase shift is
, then we can set up the equation
where we determine
.
The midline (or vertical shift),
, is the horizontal line that passes through between the maximum and minimum points, which the function oscillates. In this case, the midline would be located at the line
, therefore,
.
Putting all our information together, your final equation is:
