Replace x with 10 and simplify the fraction.
40/10 = 4/1 = 4
The answer is 4
It would be the last answer, you can't simplify
Answer:
The RATE OF CHANGE of a function is the size of the change in the Y-axis variable compared to the size of the change in the X-axis variable
Formula: Y2-Y1/ X2-X1
Words: Change in Y over change in X.
Parallel = same slope
f(x) = 4x + b
8 = 4(3) + b, b = -4
Equation: f(x) = 4x - 4
Step-by-step explanation:
let the eqn be y = mx + b.
m = 200/(900 - 700) = 1
sub (700, 0):
0 = 700 + b
b = -700
therefore eqn is y = x - 700
