Write the slope-intercept form of the equation of the line described below.

prisoha [69]

The equation of the line is $y=-\frac{2}{5}x-5$

Explanation:

Given that the line passes through the points (-5,-3)

The slope of the line is $m=-\frac{2}{5}$

We need to determine the equation of the line.

<u>Equation of the line:</u>

The equation of the line can be determined using the formula,

$y-y_1=m(x-x_1)$

Let us substitute the points (-5,-3) and the slope $m=-\frac{2}{5}$ in the above formula.

Thus, we have;

$y+3=-\frac{2}{5}(x+5)$

Simplifying, we get;

$y+3=-\frac{2}{5}x-2$

Subtracting 3 from both sides of the equation, we get;

$y=-\frac{2}{5}x-5$

Hence, the equation of the line in slope - intercept form is $y=-\frac{2}{5}x-5$

Given 5n² + 6n + 7 = n² - 4n : a. Find the value of the discriminant. b. State the number and type of roots/solutions/zeros.[2 r

Vika [28.1K]

$\bf 5n^2+6n+7=n^2-4n\implies 5n^2+6n+7-n^2+4n=0
\\\\\\
4n^2+10n+7=0\\\\
-------------------------------\\\\
\begin{array}{llccll}
&{{ 4}}x^2&{{ +10}}x&{{ +7}}\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}
\\\\\\
discriminant\implies b^2-4ac=
\begin{cases}
0&\textit{one solution}\\
positive&\textit{two solutions}\\
negative&\textit{no solution}
\end{cases}$

if you get a positive value, that means 2 real solutions
if you get 0, means 1 real solution only
if you get a negative value, is an imaginary root solution, same as saying no solution.
