Answer:
see below
Step-by-step explanation:
y = −1.5x + 3.5 is the equation of the line
Points: (5,-4), (-1,5)
Formula (y=mx+c): y = −1.5x + 3.5
Slope m: -1.5
Y-intercept b: 3.5
Parallel lines: −1.5x + any number
Perpendicular lines: 0.666666666667x + any number
X = -0.94339622
Hope this helps!

Thus .7 *90 = $63
Answer:Area of the lawn is 1725 ft^2
Step-by-step explanation:
The yard is in the shape of a trapezoid. The area of the lawn can be determined by finding the area of the trapezoid. The formula for determining the area of a trapezoid is expressed as
Area of trapezoid =
1/2(a + b)h
Where
a is the length of one of the parallel sides of the trapezoid
b is the length of the other parallel side of the trapezoid.
h is the perpendicular height of the the trapezoid.
From the diagram,
a = 50 feet
b = 65 feet
h = 30 feet
Area of the lawn = 1/2(50 + 65)× 30
= 1/2 × 115 × 30 = 1725 ft^2
