Step-by-step explanation:
Hey there!
The points are (x,2) and (8,17).
The slope given is 3.
Now,
Using slope formula.
[tex]slope = \frac{y2 - y1}{x2 - x1} [/tex]
Put all values.
[tex]3 = \frac{17 - 2}{8 - x} [/tex]
Simplify them to get answer.
[tex]3 = \frac{15}{8 - x} [/tex]
[tex]3(8 - x) = 15[/tex]
[tex]24 - 3x = 15[/tex]
[tex]24 - 15 = 3x[/tex]
[tex]x = \frac{9}{3} [/tex]
Therefore the value of x is 3.
Hope it helps...
