Answer:
Step-by-step explanation:
Sure! So, we need to divide by 1.6 on each side to isolate the x.
1.6x / 1.6 is just x. We need to divide by the same on the other side too!
1.28 / 1.6 is 0.8.
So x = 0.8
The equation of the line would be
y = mx+b
where m is the slope, b is the y intercept.
<span>The line will form a triangular region in the first quadrant. Its area would be 1/2 base times height. The height is the y intercept
and the base is y intercept divided by slope. Therefore,</span>
A = b^2/2m
At point (2,5)
5 = 2m+b
Substitute that in the area
A = b^2/5-b
to find the least area, differentiate the area with respect to the height and equate it to 0
dA/db = 0
<span>find b and
use that to find m. Then, you can have the equation of the line.</span>
