Answer:
y = -2x + 2
Step-by-step explanation:
The equation of a line is y = mx + b.
First we want to find m, the slope. We can used the coordinates to do so:
Now we know that the equation is y = -2x + b. We can plug in the coordinate (3, -4) to find b.
So the equation is y = -2x + 2.
Answer:
y =
Step-by-step explanation:
given y varies as the square of x then the equation relating them is
y = kx² ← k is the constant of variation
to find k use the given condition y = 25 when x = 3
k = =
⇒ y = x²
when x = 2
y = × 4 =
