Answer:
y = -2x + 9
Step-by-step explanation:
The slope of the line can be found from 2 points.
(y2-y1)/(x2-x1)
7-3/1-3
4/-2
= -2
-2 is the slope.
The y-intercept is 9.
The equation of a line is y=mx+b.
m is the slope, and b is the y-intercept.
y = -2x + 9
See picture for reply and solution steps.
9.41 inches to the nearest hundredth
By proportion it is 800 / 85
= 9.41 inches.

<u>Answer</u> :-</h2>
To find the cost of planting grass , we have to find area of the field.
Area of field = Length × Breadth


Now convert into hectare.
1 hectare = 10000m sq.
51000 / 10000
So area field = 5.1 hectare sq.
Now cost = 5.1 x 0.80 p
