Answer:

y=\frac{5}{8}x

y=\frac{15}{8}, when x=3.

Step-by-step explanation:

We have been given that  y varies directly with x, and y=15 when x=24.

We know that two direct proportional quantities are in form y=kx, where k is constant of proportionality.

Let us find constant of proportionality by substituting y=15 and x=24 in above equation.

15=k*24

\frac{15}{24}=\frac{k*24}{24}

\frac{3*5}{3*8}=k

\frac{5}{8}=k

Therefore, our required equation would be y=\frac{5}{8}x.

Let us substitute x=3 in the equation.

y=\frac{5}{8}(3)

y=\frac{15}{8}

Therefore, the value of y is \frac{15}{8}.

Just set up a proportion with the original numbers and then the numbers you want to find like so: (x1/y1)=(x2/y2) and since you want to find the second y value, just leave y as a variable like so: (15/24)=(3/y) after this just cross multiply and get the answer: 15y=72.....y=4.8

We know that the form of line passing through point (x₀ , y₀) and having slope m is : y - y₀ = m(x - x₀)

Here the line passes through the point (-2 ,9)

x₀ = -2 and y₀ = 9 and Given : Slope(m) = -14

Equation of the line :

⇒ y - 9 = -14(x + 2)
