3rd one
Reason:
Point slope formula: y-y1=m(x-x1)
y1=-4
x1=1
m=1/2
Put it all together and you get a final answer of:
y-(-4)=1/2(x-1)
two negatives make one positive
so,
final answer:y+4=1/2(x-1)
Answer:
Area is greater than 
sq ft.
Step-by-step explanation:
Length of rectangular sign board = ft
Width of rectangular sign board = 
ft
Area of a rectangle is given by the formula:
To find the area, we are going to multiply with .
is greater than 1.
Therefore the multiplication will be greater than .
Hence, we can say that area will be greater than sq ft.
Area of the sign:
Answer:102.22
Step-by-step explanation:
Every line that does not have the slope of 2/7 is perpendicular to this line.
In order to find this fact, we first must find what is perpendicular. To do that, we first have to find the slope of this line. We can do this by solving for y.
7x + 2y = 3
2y = -7x + 3
y = -7/2x + 3/2
Now we can take the slope of -7/2 and flip and negate it. This will give us the perpendicular slope (2/7). Now we know any line that does not have this slope is not perpendicular to this line.
