Answer:
y -5 = -7(x +5)
Step-by-step explanation:
The point-slope form of the equation for a line is usually used for this purpose. For point (h, k), the line with slope m through it is given by ...
y -k = m(x -h)
Filling in the given numbers, you get the equation ...
y -5 = -7(x +5)
_____
This can be rearranged to any of several other forms:
y = -7x -30 . . . . . slope-intercept form
7x + y = -30 . . . . standard form
x/(-30/7) + y/(-30) = 1 . . . . . intercept form
Answer:
(Square, Right Triangle)
18 meters²
Step-by-step explanation:
You can divide the shape into a square and right triangle, see the attachment :)
The area of the square is the length times the width. So,
3 · 3 = 9
The area of the square is 9 m².
The triangle's area is the base times the height divided by 2. So,
6 · 3 = 18
18 / 2 = 9
The triangle has an area of 9 m².
Add these together.
9 + 9 = 18
The area is 18 meters².
The answer is they are reciprocal.
(1) Express both equations in the slope-intercept form: y = mx + b, where m is slope:
<span> 8x - 9y = 5
9y = 8x - 5
y = 8/9x - 5/9
m1 = 8/9
</span><span>9x - 8y = 1
8y = 9x - 1
y = 9/8x - 1/8
m2 = 9/8
So, m1 = 8/9 and m2 = 9/8. They are reciprocal</span>
