Step-by-step explanation:

Hey there!

The given points are; (2,2) and (5,y).

Slope (m) =2

<u>Usi</u><u>ng</u><u> formula</u><u> for</u><u> </u><u>slope</u><u>,</u><u> </u><u>we</u><u> </u><u>get</u><u>;</u>

<u>m =  \frac{y2 - y1}{x2 - x1}</u>

<u>Pu</u><u>t</u><u> all</u><u> </u><u>v</u><u>alues</u><u>.</u>

<u>2 =  \frac{y - 2}{5 - 2}</u>

<u>Simpl</u><u>ify</u><u> </u><u>it</u><u> </u><u>to</u><u> </u><u>get</u><u> </u><u>valu</u><u>e</u><u> of</u><u>"</u><u>y</u><u>"</u><u>.</u>

<u>2 =  \frac{y - 2}{3}</u>

<u>6 = y - 2</u>

<u>y = 6 + 2</u>

<u>Therefore</u><u>,</u><u> </u><u>y</u><u>=</u><u> </u><u>8</u><u>.</u>
