The point-slope form:

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

We have

$m=2,\ (1,\ 7)$

Substitute:

$y-7=2(x-1)\qquad|\text{use distributive property}\\\\y-7=2x-2\qquad|+7\\\\y=2x+5\qquad|-5\\\\y-5=2x\qquad|-y\\\\2x-y=-5$

<h3>Answer:</h3><h3>point-slope form: y - 7 = 2(x - 1)</h3><h3>slope-intercept form: y = 2x + 5</h3><h3>standard form: 2x - y = -5</h3>

Recall the dot-product is just <a,b> • <c,d> => a*c + b*d.

therefore here is just 5*(-8) + 7* 2, or namely -26.
