\bf (\stackrel{x_1}{-3}~,~\stackrel{y_1}{11})\qquad (\stackrel{x_2}{0}~,~\stackrel{y_2}{2}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{2-11}{0-(-3)}\implies \cfrac{-9}{0+3}\implies \cfrac{-9}{3}\implies -3 \\\\\\


\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-11=-3[x-(-3)]\implies y-11=-3(x+3) \\\\\\ y-11=-3x-9\implies y=-3x+2\implies \stackrel{\textit{using function notation}}{f(x)=-3x+2}

In a blueprint for a house, the scale is 1 inch = 5 feet. In the blueprint, one room
Dimas [21]

for each inch is 5 feet, so for each 0.5 aka 1/2 inch, it would be 2.5 inches

2in: 5+5=10ft

2.5in: 5+5+2.5=12.5ft

or just simply mutiply by 2

2(5)= 10ft

2.5 inches so 2.5(5)=12.5

The dimensions of the actual room are 10 feet by 12.5 feet

Solve this by substitution
frozen [14]

Answer:

y= 1 and x=-2

Step-by-step explanation:

Since they both equal y, you can equal them to each other:

x + 3 = 2x + 5

Then solve:

x - x + 3 = 2x - x + 5

3 - 5 = x + 5 - 5

-2 = x

Substitute x in either equation to solve for y:

y = (-2) +3

y = 1

Or the other equation:

y = 2(-2) + 5

y = -4 + 5

y = 1

hope this helps :)
