Slope : - 9/7 point : ( -7,4 )
dolphi86 [110]
To form an equation with the given information, we use the formula :

y = mx + b, m being the slope and b being the y-intercept.

Since it is given that the slope is -9/7, we substitute m with -9/7.

y = -9/7x + b

To find b, we will substitute the known coordinates into the equation :
At point (-7 , 4), x = -7, y = 4

4 = -9/7 (-7) + b
4  = 9 + b
b = 4 - 9
b = -5

Now we know that b = -5, we will substitute b = -5 into the equation that we found earlier, y = -9/7 x + b :

y = - 9/7x - 5

To make it more readable, we can multiply the equation by 7:
7y = -9x - 5
7y + 9x + 5 = 0

-----------------------------------------------------------
Answer : 7y + 9x + 5 = 0

Y
juin [17]

Answer:

y = 75

Step-by-step explanation:

Given that:

   y \alpha \sqrt{x}

⇒ y = k\sqrt{x}

where k is the constant of proportionality.

When y = 45, x = 81, then;

45 = k\sqrt{81}

45 = 9 k

k = \frac{45}{9}

  = 5

k = 5

So that,

y = 5\sqrt{x}

the value of y when x = 225 is;

y = 5\sqrt{x}

  = 5 x \sqrt{225}

  = 5 x 15

y = 75
