Suppose Y varies directly with X, and Y = 15 and X = 5. Write a direct variation equation that relates X and Y. What is the valu
Oksana_A [137]

Answer:

Step-by-step explanation:

If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. Also, a decrease in the value of one variable would cause a corresponding decrease in the other variable.

Given that Y varies directly with X, and Y = 15 and X = 5, if we introduce a constant of proportionality, k, the expression becomes

15 = 5k

k = 15/5

k = 3

The equation would be

Y = 3X

Therefore, when X = 9, the value of Y would be

Y = 3 × 9

Y = 27

Find the value of R so that the line that passes through each pair of points has the given slope: (8, -2 ), (r, -6), m=-4
kondor19780726 [428]
\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%   (a,b)
&({{ 8}}\quad ,&{{ -2}})\quad 
%   (c,d)
&({{ r}}\quad ,&{{ -6}})
\end{array}
\\\\\\
% slope  = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{-6-(-2)}{r-8}=-4
\\\\\\
\cfrac{-6+2}{r-8}=-4\implies -4=-4(r-8)\implies \cfrac{-4}{-4}=r-8\\\\\\ 1+8=r

Answer:

The equation of the straight line in point-slope form

                            y - 4 = \frac{7}{9}  (x-0)

The equation of the straight line

                         7x -9y +36 =0

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the points (0,4) and (-9,-3)

The slope of the line

         m = \frac{y_{2} - y_{1} }{x_{2}- x_{1}  } = \frac{-3-4}{-9-0} = \frac{7}{9}

<u><em>Step(ii):-</em></u>

    Equation of the straight line passing through the point (0,4) and having slope m = 7/9

          y - y_{1} = m (x-x_{1} )

         y - 4 = \frac{7}{9}  (x-0)

      9 y - 36 = 7x

              9y = 7x + 36

          y = \frac{7x}{9} +\frac{36}{9}

Slope - intercept form  

                            y = \frac{7x}{9} +4

<u><em>Final answer:-</em></u>

The equation of the straight line in point-slope form

                            y - 4 = \frac{7}{9}  (x-0)

The equation of the straight line

                         7x -9y +36 =0
