Answer: y - 1 = –(x –7)
or y –5 = –1(x –3)
The attachment shows the graph of these equations (identical)
Step-by-step explanation:
The basic form for a point-slope equation is
y - b = m(x - a)
a is the x-value from the given coordinate, b is the y-value form the given coordinate, m is the slope. x and y are the variables in the function.
To find the slope, m, use the given coordinates. Get the difference in the y-values and divide by the difference in the x-values. This is "rise over run."
Subtract the first coordinate from the second coordinate.
Given coordinate points: (3,5) and (7,1) substitute values:
m= 1 –5 / 7 –3 becomes m= –4/4 so the slope, m = –4/4
That is –1 The "1" is "understood," so only the negative sign represents the slope in the equation
To write the equation: Take the basic form, substitute b and a values from either given coordinate. And use the value of m we just calculated.
y - b = m(x - a) Using the second coordinate: (7,1)
y - 1 = –(x –7)
or using the first coordinate:
y –5 = –(x –3)
Answer:
Option 4
Step-by-step explanation:
Given function is,
Steps to get the inverse of the given function,
Step 1,
Convert the function into equation,
Step 2,
Interchange the variables 'x' and 'y',
Step 3,
Solve the equation for the value of y,
Step 4,
Convert the equation into inverse function,
For x-intercepts,
Substitute y = 0,
Therefore, x-intercept of the inverse function is .
Option 4 will be the answer.
