Answer:
y = 4x–5
Step-by-step explanation:
Slope intercept form is y = mx +b. We can rearrange the equation to fit slope intercept form.
–2y = –8x + 10 (we get this by subtracting 8x from both sides)
In order to isolate the y, we divide both sides by –2.
=
+
–2 divided by –2 equals 1, –8 divided by –2 equals 4, and 10 divided by –2 equals 5.
Therefore, the answer is y = 4x–5.
Answer:
D
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here { a, b ] = [ - 1, 2 ], thus
f(b) = 4 ← from (2, 4 )
f(a) = ← from (- 1,
) , thus
average rate of change = =
