Answer:
<u>Slope = 3</u>
Step-by-step explanation:
Slope is calculated as the "Rise/Run" of a straight line. The Rise is the change in the value of y, or the amount y changes per change in x. Run is the change in the x value. A line with a run of 3 and a rise of 9 is calculated as:
Rise/Run = 9/3 or 3
This means that the value of y will increase by 3 for every increase of 1 in the value of 3.
Slope in "m" in the slope-intercept form of a straight line equation: y = mx + b
The line y = 3x + 2 tells us the it has a slope of 3 and intercepts the y axis at x = 2.
Example points (y = 3x + 2)
(0,2)
(1,5)
(4,14)
Note that y changes by 12 when x changes by 4. Rise/Run = 12/4 or 3.
Answer:
108
Step-by-step explanation:
cross multiply fractions:
12/72 = 18/x
x = 108
Lets cut this shape into rectangles and triangles.
The rectangles will be 7x3 and 3x4
So that is 21 sq rt and 12 sq ft.
Now the triangles.
One will be 2*3/2 and the other will be 4*3/2
So that is 3 sq ft and 6 sq ft.
In total the hole is 42 sq ft.
