Answer: -3 + 4 = 1
==================================================
Explanation:
We start at the bottom layer.
That arrow on the bottom layer goes from 0 to -3. In short, it represents the number -3.
The upper arrow moves from -3 to +1 or simply 1. This is a distance of 4 spaces. So we add on 4.
Overall, this diagram represents -3+4 = 1
Answer:
y = 4x - 11 .
Step-by-step explanation:
The line y = 4x - 9 has a slope of 4 so our line will also contain 4x.
Using the point-slope form of the equation of a line:
y - y1 = m(x - x1) , we have m = 4 and (x1, y1) = (2, -3):
y - -3 = 4(x - 2)
y + 3 = 4x - 8
y = 4x - 11 (answer).
