Answer:
y= -7x -7
Step-by-step explanation:
All line equations can be represented in the form y = mx + c where a is the gradient or slope and b is the y intercept. (letters used for m and c may vary)
You have been given the slope, = -7 which you can put into y=mx+c
y = -7x + c
The function of a line ^^ means that for any values of x, you multiply it by -7 and add -7. The given coordinates means that when x =0, y = -7. So you can plug these into y = -7x + c , -7 = -7(0) + c . Therefore c = -7
Alternatively, since the value for c is the y intercept, the coordinates immediately give you the answer c. x = 0 which means taht the line intercepts the y axis when y = -7. hence the y intercept = -7
Answer: A. - 2.215
Step-by-step explanation:
• A residual is the difference between the actual value and the predicted value in a regression model. It represents the vertical distance from the actual point to the point on the regression line.
Hence, the residual in this case = -2.215

in function...
v = f(X - 10)
