Answer:
B
Step-by-step explanation:
you take away the 7 and it then b
The equation of the line that passes through the points (2,1) and (5,-8) is
y = -3x + 7
"When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h) Therefore, the slope of the secant line between any two points on this function is 2x + h."
Step-by-step explanation:
substitute for y
x+3+4 = -6x
x+ 7 = -6x
7 = -7x
-1 = x
y = -1+3
y = 2
