A line passes through the point (-4,3) and has a slope of -5/2
Jlenok [28]

Answer:

y=(-5/2) x -7

Step-by-step explanation:

y=mx+b

m=(-5/2)

To find b:

3=(-5/2)times"x" + b

3=(-5/2)times(-4) + b

3=  10 +b; b=-7

y=(-5/2) x -7

Ndicate the equation of the line through (2, -4) and having slope of 3/5.
lord [1]

\bf (\stackrel{x_1}{2}~,~\stackrel{y_1}{-4})~\hspace{10em} slope = m\implies \cfrac{3}{5} \\\\\\ \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-(-4)=\cfrac{3}{5}(x-2) \implies y+4=\cfrac{3}{5}x-\cfrac{6}{5} \\\\\\ y=\cfrac{3}{5}x-\cfrac{6}{5}-4\implies \implies y=\cfrac{3}{5}x-\cfrac{26}{5}

How do you factorise 2k + 10ak
wolverine [178]

Hii!

____________________________________________________________

\rightsquigarrow\circ\boldsymbol{Answer}\circ\leftharpoonup

2k(1+5a) <em>or </em>2k(5a+1)

\rightsquigarrow\circ\boldsymbol{Explanation.}\circ\leftharpoonup

First of all, let's find the common term of this binomial (an expression with two terms; the prefix bi- means "two")

Note that both terms have 2k in them. So, we factor it out.

\twoheadrightarrow\sf 2k\div2k+10ak\div2k

\bullet <em>Simplify</em>

<em />\twoheadrightarrow\sf 1+5a

\bullet <em>2k can't just vanish into thin air, so we put it outside the parentheses:</em>

<em />\twoheadrightarrow\sf 2k(1+5a)

\bullet <em>Great job! We factored the expression successfully</em>

<em />

<em>--</em>

Hope that this helped! Best wishes.
