Answer:
1.) 
2.) 
3.) 
4.) 
Step-by-step explanation:
The unit rate is also known as slope. Slope is the change in the y values over the change in the x values:

However, with certain graphs, the slope can be found in a simpler manner.
- You start at one point and move across the y-axis, then move along the x-axis until you reach another point on the same line.
- Make sure you move on the y-axis first, then the x-axis. Record the slope as spaces moved in each
- When you move up, the number will be positive
. If you move down, the number will be negative
. - If you move to the right, the number will be positive
. If you move to the left, the number will be negative
.
Answer:
30.4 feet.
Step-by-step explanation:
We have been given the length of the ramp on the blueprint is 7.6 inches. The scale on the blueprint is 1 inch to 4 feet. We are asked to find the actual length of the ramp.
We will use proportions to solve our given problem as:

Now, we will substitute the scale length of ramp in our proportion as:




Therefore, the actual length of the ramp would be 30.4 feet.
