Answer:

$y = \frac{1}{3}x - 5$

Step-by-step explanation:

Given

$slope\ (m) = \frac{1}{3}$

$y\ intercept = -5$

Required

Determine the line equation in slope intercept

The equation of a line in slope intercept is:

$y = mx + b$

Where

$m = slope = \frac{1}{3}$

$b = y\ intercept = -5$

So, $y = mx + b$ becomes

$y = \frac{1}{3}x - 5$

A metallugarist has an alloy with 6% titanium and an alloy with 20% titanium. He needs 100 grams of an alloy with 13% titanium.

dsp73

$\bf \begin{array}{lccclllll}
&amount(g)&\textit{\% of titanium}&\textit{grams of titanium}\\
&-----&-----&-------\\
\textit{6\% alloy}&x&0.06&0.06\cdot x\\
\textit{20\% alloy}&y&0.2&0.2\cdot y\\
----&-----&-----&-----\\
mixture&100&0.13&100\cdot 0.13\to 13
\end{array}$

so.. .whatever those amounts are, of "x" and "y", for the mixture,
they must add up to 100 grams, or x + y = 100

and the titanium percentage of that sum, must yield a 13 grams of titanium on those 100 grams

thus $\bf \begin{cases}
x+y=100\to y=\boxed{100-x}
\\\\
0.06x+0.2\boxed{y}=13
\end{cases}$

do the substitution, and solve for "x",

what's "y" amount? well, y = 100 - x
