For this case we have the following equation:
y = 2x - 2
For the point (1, 0) we have:
x = 1
y = 0
Substituting values we have:
0 = 2 (1) - 2
0 = 2 - 2
0 = 0
We observe that equality is fulfilled and therefore, the point belongs to the equation.

Answer:
<h2>width = 7 m</h2><h2>length = 5 m</h2>
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
Perimeter = 24m
The statement
The length is 30 m less than five times the width is written as
l = 5w - 30
Substitute the expression into the above formula and solve for the width
That's
24 = 2( 5w - 30) + 2w
24 = 10w - 60 + 2w
84 = 12w
Divide both sides by 12
w = 7
Substitute this value into l = 5w - 30
That's
l = 5(7) - 30
l = 35 - 30
l = 5
Therefore the dimensions are
width = 7 m
length = 5 m
