4.5/2.5 = y/12
y = 12 * 4.5/2.5
y = 21.6
Answer: 1) (-2,0)
2) (0,2)
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
You only need two points to find the slope.
Let's use (1,7) and (2,8).
The formula for slope is (y2-y1)/(x2-x1)
Let's plug the values in:
(8-7)/(2-1) = 1.
So, the slope is 1.
Answer:
5
Step-by-step explanation:
Do the multiplication first: 3 - (-2) becomes 3 + 2.
Thus,
3-(-2) = 5
