The amount if the original cost of the head board is $12.24
Answer:
y = 2x - 7
Step-by-step explanation:
To find the line equation we assume that its form is y = m*x + b. Where m is the slope and b is the independent variable that intercepts the Y axis.
If we have two points as P1=(x1,y1) and P2=(x2,y2) we can use the slope formula as:
m = (y2-y1)/(x2-x1)
The points given are P1=(7,7) and P2=(2,-3), then the using the slope formula we obtain:
m = (-3-7)/(2-7)
m = (-10)/(-5)
m = 2
By now the equation is y = 2x + b. To find the value of b we have to replace in the equation any point, in this case i am using P2:
-3 = 2*(2) + b
-3 = 4 + b
-3 -4 = b
-7 = b
Therefore the equation of the line is:
y = 2x - 7

Answer:
0.5x - y = 1.5
Step-by-step explanation:
First, put the equation in point slope form:
y - y1 = m(x - x1)
y + 2 = 1/2(x + 1)
Distribute the 1/2:
y + 2 = 1/2x + 1/2
Change the fractions to decimals:
y + 2 = 0.5x + 0.5
Subtract y from both sides:
2 = 0.5x - y + 0.5
Subtract 0.5 from both sides:
1.5 = 0.5x - y
Rearrange the equation:
0.5x - y = 1.5
So, the equation of the line in standard form is 0.5x - y = 1.5
There were 20 pieces of wood left.
Work:
420 ÷ 7 = 60
60 - 40 = 20
Your answer is 20.
Hope this helps!
