Y = mx + b
m = slope = -3
y = -3x + b
We need to find b, so plug 7 for x and 8 for y
8 = -3*7 + b
8 = -21 + b
Add 21
29 = b
So the equation is y = -3x + 29.
First you write it as a fraction as
16/28 and 240/560
240/560 can be simplified to 27/28
16/28 is not equivalent to 27/28
Hope this helps ;)

Step-by-step explanation:
Answer:
112°
Step-by-step explanation:
the sum of the 4 angles of a quadrilateral = 360°
To find the fourth angle, sum the 3 given angles and subtract from 360
fourth angle = 360° - (100 + 104 + 44 )° = 360° - 248° = 112°
