The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.
1. a) equation of the line :
y - intercept = -7
so, it will pass through point (0, -7)
and if we plug the value of x as 5, we get
so, it will pass through point (5, -5) too
now, just plot the points (0 , -7) and (5 , -5) and join them.
2. b) equation of line is :
here, y - intercept = 5
so the line passes through point (0 , 5)
now, Plugging the value of x = 1 we get :
so, the given line passes through point (1 , 2)
plotting the points, we can get our required line.
Answer:
2x - 7
Step-by-step explanation:
Twice a number x means x times 2, which can be written as 2x
Minus 17 from 2x
Since both terms have the same variable to the same power, you can simply add the coefficients...
14x^7
