The slope is 2
y=2x + b
Plug in a point to solve for b
8 = 2(3) + b
8 = 6 + b
b = 2
The equation is y = 2x + 2
Divide both by 18.
<span>140/18=7.78 </span>
<span>So... $7.78 per foot</span>
Given equation is y=2x+7 and 
Let's simplify the 2nd equation
before we can start graph so that calculation will be easy

multiply both sides by 2 to cancel out fractions

y=2x+7
which is exactly same as the first equatoin so graph of both will be exactly same and solution will be infinitely many solutions.
y=2x+7 has y-intercept 7 so first point will be (0,7). Slope is 2 so rise 2 unit up then 1 right and graph the new point.
Answer:
Step-by-step explanation:
<u>The scale is </u>
- 15 in ÷ 24 feet =
- 15 in ÷ 24*12 in =
- 15 in ÷ 288 in =
- 5 in ÷ 96 in =
- 5 ÷ 96
For the X intercept you set y = 0 and solve for x
Y =

x + 9
0=

x + 9 subtract 9 from both sides
-9 =

divide both sides by 3
-3 = -8x divide both sides by -8

= x
X-intercept = (

, 0)
