Answer: w = 3z + 2
Step-by-step explanation:
1) On the coordinate graph, we can see that the line starts on 2 on the y-axis.
2) Using the mx + b format and it's rules to apply to the line, mx is the growth and b is the starting point.
3) 2 is the starting point of the line. So we would insert 2 in place of b on the mx + b equation: mx + 2. This means that 2 should be in place of b in our answer because the line starts at 2 on the y-axis.
4) Now we have a partial part of our answer, which limits us to two answers:
What they have in common is that they both have 2 in the b place.
5) Now we have to look at the growth. On the coordinate graph, we can see that the line extends upwards 3 units up and move one unit to the right.
6) This concludes that the growth is \frac{3}{1} or 3. So out of our two answers,
One of them should have 3 in the m place.
7) We are left with w = 3z + 2, as it correlates with the growth and starting point of the line.
