Answer:
y= 1/3 x +5
Step-by-step explanation:
To find the slope, we take two points
(0,5) and (15,10)
The slope is found by the formula
m = (y2-y1)/ (x2-x1)
= (10-5)/(15-0)
= 5/15
= 1/3
The slope is 1/3
The y intercept is found when x=0
When x=0 y=5
The slope intercept form of the line is
y=mx+b where m is the slope and b is the y intercept
y= 1/3 x +5
The solution would be x = 5,1
3x6=18 3x4=12 12+18=30 so the actual area is 30

The solution is
<u>EXPLANATION</u>
We have
and
Let us substitute equation (1) in to equation (2). This gives us,
We rewrite this as a quadratic equation as the highest degree is 2.
This implies that
we factor to obtain,
This means,
We substitute this values into any of the above equations, preferably equation (1)
