The line passing through the points (-7,4) and (-23,y) is parallel to a line that has a slope of -5/8. What is the value of y?
Burka [1]
Two lines that are parallel to each other, will have the same slope.

so if this line is parallel to another with a slope of -5/8, the slope of this line is also -5/8 then.  We also know that it passes through -7, 4 and -23, y, let's do some checking.

\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%   (a,b)
&({{ -7}}\quad ,&{{ 4}})\quad 
%   (c,d)
&({{ -23}}\quad ,&{{ y}})
\end{array}
\\\\\\
% slope  = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{y-4}{-23-(-7)}\implies \cfrac{y-4}{-23+7}
\\\\\\
\cfrac{y-4}{-16}=\boxed{-\cfrac{5}{8}}\implies 8y-32=80\implies 8y=112
\\\\\\
y=\cfrac{112}{8}\implies y=14

The values of x and y vary directly and one pair of values are given. Write an equation that relates x and y. x=-4,y=6
makkiz [27]

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 x varies directly with y, if we introduce a constant of proportionality, k, the expression becomes

x = ky

If x = - 4 when y = 6, then

- 4 = 6k

k = - 4/6 = - 2/3

Therefore, the equation that relates x and y is

x = -2y/3
