2x+3y=-12\ \ \ \Rightarrow\ \ \ 3y=-2x-12\ \ \ \Rightarrow\ \ \ y=- \frac{2}{3} x-4\\\\y=mx+b\ \ ||\ \ y=- \frac{2}{3} x-4\ \ \ \Leftrightarrow\ \ \ m=-\frac{2}{3}\\\\the\ point\ slope\ form:\ y-y_1=m(x-x_1)\ \ \ and\ \ \ (x_1,y_1)=(2,5)\\\\y-5=-\frac{2}{3}(x-2) \ \ \Rightarrow\ \ \ y-5=-\frac{2}{3}x+\frac{4}{3}\ \ \ \Rightarrow\ \ \ y=-\frac{2}{3}x+5+1\frac{1}{3} \\\\the\ slope\ intercept\ form:\ \ \ y=-\frac{2}{3}x+6\frac{1}{3}\\\\ the\ slope:\ m=- \frac{2}{3},\ \ \ the\ intercept:\ b=6\frac{1}{3}

Jlenok [28]

Answer:

5 tubes of blue paint are used for 15 tubes of white paint.

Step-by-step explanation:

Given:

To paint a mural painter uses 2 tubes of blue paint for every 6 tubes of white paint

Hence,

6 tubes of white paint = 2 tubes of blue paint

Now we need to find number of blue paint tubes used for 15 tubes of white paint.

6 tubes of white paint = 2 tubes of blue paint

15 tubes of white paint = number of blue paint tubes used for 15 tubes of white paint

Hence we will used unitary method to find the same;

Number of blue paint tubes used = \frac{15\times 2}{6} = \frac{30}{6}=5

Hence 5 tubes of blue paint are used for 15 tubes of white paint.
