Answer:
y=-2x+7
Step-by-step explanation:
Slope is y(2)-y(1)/x(2)-x(1)
I chose (1,5)(0,7) as my two points and got -2 as my slope
Then, I got (0,7) as my y-intercept because it was in the table.
So, the equation is y=-2x+7

Answer:
-1.9f-20
Step-by-step explanation:
-2.7f+0.8f-16-4
<em>Collect similar items</em>
-2.7f+0.8f=-1.9f
=-1.9f-16-4
<em>Subtract the numbers</em>
-16-4=-20
=-1.9f-20
Set the equation up as a proportion, where x = the height of the tree in feet
27/x = 4.5/5
cross multiply
(4.5)(x) = (27)(5)
(4.5)(x) = 135
divide the entire equation by 4.5 to isolate x
135/4.5 = 30
x = 30
the tree is 30 ft tall
