Answer:
1
Step-by-step explanation:
m= (y-y1)/(x-x1)
Points are (-10, -20) and (1, -9)
m= (-20+9)/(-10-1)= (-11)/(-11)= 1
m=1 to replace ? mark
-4x + 6y = -12
-4(0) + 6y = -12
0 + 6y = 12
<u>6y</u> = <u>12</u>
6 6
y = 2
The y-intercept of the equation is 2.
The interior angles of a quadrilateral shape add up to 360 so 116+93+45+x = 360 with x equaling 106
