Answer:
y = -1/2x - 4
Step-by-step explanation:
The slope intercept form of a line is y = mx + b. The slope is -1/2 so substitute m = -1/2. The y-intercept is b so substitute b = -4.
y = -1/2x - 4
The materials were charged at a loading charge of 80.00% of their cost.
The total charge was $720 and included both the material charge and the labor charge.
The first thing to do is therefore find out the cost of the materials without the labor charge:
<em>= Total cost - labor charge</em>
= 720 - (6 labor hours x 75 per labor hour)
= 720 - 450
= $270
The total cost of materials is $270. To find the material loading charge, use the formula:
<em>= (Total cost of materials - Cost of materials used) / Cost of materials used x 100%</em>
= (270 - 150) / 150 x 100%
= 120 / 150 x 100%
= 80%
In conclusion, the material loading charge was 80.00%.

Answer:
If we are to treat these as two ordered pairs, then the rate of change is 0.90625
Step-by-step explanation:
To find this, use the slope equation with the ordered pairs.
m(slope) = (y2 - y1)/(x2 - x1)
m = (11 9/16 - 9 12/16)/(12 - 10)
m = (1 13/16)/2
m = 1.8125/2
m = 0.90625
Now we know that this could be a function since we have a constant slope.
