$350 Salary a week + $4,500 Sales times 4.5%= $202.50 + $350= $552.50
$786 Salary per week + $14,420 Sales times 3.25% = $463.125+Salary ($786) = $$1,1249.13
$245 Salary a week +12 % in Sales of $8,958.33 = 1074.9996 + 245 in Salary = 1,319.9996 or $1,320

Find the equation of a line with a slope of 13/2<br> that passes through the point (−2, — 10).

Darya [45]

Answer: $y=\frac{13}{2} x+3$

Step-by-step explanation:

Remember the point-slope equation which is $y-y_{1} = m(x-x_{1} )$ where $(x_{1} , y_{1} )$ is your <u>point</u> and $m$ is your <u>slope.</u>

<u />

Given that we substitute what you have:

$y-(-10) =\frac{13}{2} (x - (-2))$

Minus and minus give us positive:

$y+10 =\frac{13}{2} (x +2)$

Multiply slope into the parenthesis:

$y+10= \frac{13}{2}x + \frac{13}{2}*2\\$

Calculate it:

$y+10= \frac{13}{2}x +13$

Isolate the $y$ by subtracting 10 from both sides:

$y=\frac{13}{2} x + 13 -10$

Your final equation is:

$y=\frac{13}{2} x +3$

Hope this makes sense!

And here's the graph to prove that the line actually goes through the point $(-2,-10)$ :
