Answer:
A
Step-by-step explanation:
The line cuts the y at positive two. The rise over run of the slope is -3/1, or 3.
Just had a test on these kinds of problems and i got 100.
A.) 10x + 7.5 (0) =420
10x = 420
420 / 10 = 42
x = 42 > ( 42,0 )
10(0) + 7.5y = 420
7.5y = 420
420 / 7.25 = 56
y = 56 > ( 0,56 )
(42,0) (0,56)
B.) The x intercept means that there was 42 ,minutes spent biking. The y intercept means that there was 56 minutes spent in line skating.
C.) (21 ,28) - (14,37) - (28,18)
Answer: 7,044.6
Step-by-step explanation:
35223/5 = 7,044.6
-3/2
slope = rise/run
We can use the two points to calculate rise (y value change) and run (x value change)
slope = (-6)/4 = -3/2
