First thing we need to do is find the slope. since this equation is already in slope intercept form, which is y = mx + b, the slope is already shown. It is 1/2
The slope of the line perpendicular to the given line is the negative inverse of the slope. The negative inverse of 1/2 is -2.
Next, use the slope we determined was the negative inverse ( -2 ) and the given point ( 1,3 ) to write the equation of the line in point slope form. The formula is y − y1 = m(x − x1).
With all the correct numbers plugged in, The equation is:
y - 3 = -2 ( x - 1 )

Experimental probability is if an experiment was actually run. If those values are the result of an experiment, then the probability is desired value (white) over total possibilities.
or 0.6
Step-by-step explanation:
- p(x,y)= (x1+ x2/2, y1 + y2/2)
- p ( x,y)(-3+7/2,2+5/2)
- (2,7/2)
For this question, find the area of each individual figure and then add all of them together.
Let's start with the triangles. To find the area of a triangle, use the formula A =
bh (b = base and h = height).
A =
bh
A =
(30)(40)
A =
(1200)
A =
A = 600m²
There are 4 triangles, so multiply the area of one triangle by 4 to find the area of all 4 triangles.
(600)(4) = 2400m²
Now we can find the area of the square. To find the area of a square, simply multiply the length x width (or square one side).
A = l x w
A = (30)(30)
A = 900m²
Add together the area of the triangles and the area of the square to get the total area:
2400 + 900 =
3300m²
