Answer:
Slope = -1/4
Y-intercept = 50
Step-by-step explanation:
Change in y/ change in x = slope
75/-100 = -1/4
For y, the numbers decrease 25 each time so the change in y is -25.
For x, the numbers increase 100 each time so the change in x would be 100.
The fraction you have left is -25/100
Now, you simplify -25/100 and you get -1/4.
The y-intercept is 50 because x is 0 at the same time in the chart.
13a.) If you're dividing and the base (in this case the base is 10) is the same, subtract the exponents.

13b.) If you're multiplying and the base is the same, then you add the exponents:

13c.) This is similar to 13b:
Answer:
275.04
Step-by-step explanation:
76.4 x 3.6 = 275.04
-2x - 3x = -5x
8 - 4 = 4
-5x + 4
