Answer:
y = - 2x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (8, - 9) and (x₂, y₂ ) = (- 4, 15)
m = 
= 
= - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, - 9), then
- 9 = - 16 + c ⇒ c = - 9 + 16 = 7
y = - 2x + 7 ← equation of line
To solve this relationship simply make them equal to each other and find the correct value to multiply both the top and cotton numbers and solve,
In this case because of the initial ratio of 1:9, if the bonsai ficus is 6 then 54 inches would be the full size.
Answer:
r≥2.5
it can't be < because the green dot is filled in
r is larger than 2.5 because the arrow goes to the right
Answer: Slope is m = 2/3
Step-by-step explanation:
-You have exactly four points on a table:
-Use the slope formula and use any two points from those four points in order to find the slope:
-The two points I use are 
and 
for the equation:
So, the slope of the table is 
.
I think it is c, I could be wrong though
