Answer:
-3, 2
Step-by-step explanation:
The basic form of linear function is
y=ax+b
For finding the slope, use the slope formula.
(4-2)/(-2+1)= 2/-1=-2
We first found a which is -2.
Then insert any point to find the value of b. In this case, I will insert (1,-2).
-2=-2+b
b=-2+2=0
The linear graph is y=-2x
The tree would be 10 feet tall
Answer:2:4:5
Step-by-step explanation:
It their ages are 15, 35, 45 because we know 7 in that ratio is 35(25+10)
Then if you add 5 to all their current ages:20, 40, 50
And you can simplify that to:2,4,5
