Answer:
13.5
Explanation:
The equation to find the slope (another word for the rate of change) of the line is (y2-y1)/(x2-x1) when the given points are (x1,y1) and (x2,y2).
When we plug in the given points, (3,-7) and (5,20) we can start solving.
(y2-y1)/(x2-x1)
(20-(-7))/(5-3)
Two negatives make a positive
= (20+7)/(5-3)
= 27/2
= 13.5
I hope this helps!
There is exactly one solution. 9x + 16 = 4x simplifies to 5x = 16. Dividing both sides by 5, we get
x = 16/5 (answer) (There is exactly ONE solution).
Answer:
x=2-1/2y
Step-by-step explanation:
12x+6y=24
12x=24-6y
x=24/12-6/12y
x=2-1/2y
