Answer:

Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
The slope can be found from two points.

The two points from the graph are (1, 9) and (2, 12).
Plugging in the values and evaluating.



The slope of the line is 3.
The y-intercept of the line is where the line cross the y-axis.
The line crosses the y-axis at (0, 6).

The slope-intercept form of the line is:

Answer: 1. is A
3. -3/5
4. 9/16
Step-by-step explanation: idk how to solve the other two
Answer:
Step-by-step explanation:
Sally owes 7 dollars to Matthew. She opens her piggy bank and takes out 7 dollars. Now, how much money does she owe to Matthew?
-7 + 7 = 0
-7 + 7 is the same as 7 - 7
You can clearly see that 7-7 is 0.
Set up a ratio:
1/50 = x/480
Cross multiply:
50x = 480
Divide both sides by 50:
X = 9.6
The distance on the map is 9.6 cm
