The coordinates below lie on the line with the given slope. find the missing coordinate value. (2,2) (5,y) slope = 2

vodka [1.7K]

Step-by-step explanation:

Hey there!

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

Slope (m) =2

Using formula for slope, we get;

$m = \frac{y2 - y1}{x2 - x1}$

Put all values.

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

Simplify it to get value of"y".

$2 = \frac{y - 2}{3}$

$6 = y - 2$

$y = 6 + 2$

Therefore, y= 8.

Hope it helps...

assuming you meant to simplify above,

$\bf (8+7i)+(7-3i)\implies \stackrel{\textit{adding like terms}}{15+4i}$
