First of all, remember what the equation of a line is:
Where:
m=slope
b=y-intercept.
Given this information, we can start by plugging in what we know, we are given the slope which is 2 so we can fill that in, remember m=slope
Because we were given the point (14,3)
</span>
We need to find the value of b. The 2 is already set and x and y are variables. We want the equation for the line that specifically passes through the given point (14,3).
<span>Plug in for x the number 14 and for y the number 3:</span>(14,3).
y=mx+b or 3=2 × 14+b,
solving for b: b=3-(2)(14). b=-25.<span>Plug that in for b:
</span><span>y=2x-25
<span>Final answer:
</span><span>y=2x-25</span></span><span><span>

Answer:
60 tiles.
Step-by-step explanation:
$15.00 per tile plus a flat fee of $378.00 that charges Tile All.
Therefore, for x number of tiles, the total cost of installation will be
C = 378 + 15x ........... (1)
Again, $14.50 per tiles plus a flat fee of $550.00 that charges Kitchen Plus. Amanda has at Kitchen Plus, a 10% discount coupon.
Therefore, for x tiles installation the charges will be
.......... (2) (Answer)
Now, if for x number of tiles both the company charges the same, then
378 + 15x = 495 + 13.05x (From equations (1) and (2)}
⇒ 1.95x = 117
⇒ x = 60 tiles. (Answer)
