Answer:
m = 35
Step-by-step explanation:
∵ m ∝ xy
∴ m = kxy
∵ m = 7 when x = 3 and y = 15
∴ 7 = k (3) (15)
∴ 7 = 45k ⇒ ∴ k = 7/45
∴ m = 7/45 xy
∵ x = 25 and y = 9
∴ m = (7/45) (25)(9) = 35
X + y + 3 = 0

Remember that the slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
Let's first find the slope. Below is how you find the slope using two points:
The formula for slope is
In this case we have the two points:
(-1, -5) and (-3, -7)
This means that:
^^^Plug these numbers into the formula for slope...
1
^^^This is your slope
This is the formula we have so far:
y = 1x + b
OR
y = x + b
Now we must find b
To do that you must plug in one of the given points the line goes through in the x and y of the equation.
(-1, -5)
-5 = 1(-1) + b
-5 = -1 + b
-4 = b
(D) y = x - 4
