y2-y1/x2-x1
78.3-0/3-0=78.3/3=26.1
Answer for (a) is 26.1
(b):
Use points (4, 147.6) and (9, 287.1)
Use slope formula.
y2-y1/x2-x1
287.1-147.6/9-4=139.5/5=27.9
The answer for (b) is 27.9
Hope this helps!
Please mark as brainliest if correct!
Have a great day!
First you can take out a 3. And an x and a y. Thus, 3xy(3x+4y) is the answer.
Ok The answer is : -7
Simply -7 to 7:
