The given equation is in the point-slope form. The slope can be obtained by simple identification of the parts of the equation. This is shown below:
Given equation:
(y - 3) = -2 (x - 4)
y - y1 = m(x - x1)
Where slope, m = -2
The slope of a line perpendicular to the line CD is the negative reciprocal of the slope of the line CD. Therefore:
Slope = 1/2
Answer:
c
Step-by-step explanation:
Length of the perpendicular "" = 5.
Length of the hypotenuse "" = 12.
The length of the missing side ''".
The length of the missing side (base) "" is .
Using Pythagoras theorem, we have
Hence verified. ✔
It will help to graph it, so that you can see the shape. However, you can also just solve it by looking at the vertices. If you graph it, you'll see that the shape is a trapezoid. The two bases are 4 and 6, while the height is 5 - 1 = 4. So, we solve by using the equation for the area of a trapezoid: (6 + 4) * 4 * .5 = 20 units squared.
To the left so
-1 - 7 = -8
answer
- 8
