1. Slope 3/4, through (4,-1)
y = 3/4 x + b
-1 = 3/4(4) + b
-1 = 3 + b
-1 - 3 = b
-4 = b
y = 3/4 x - 4
2. Slope = - 1/2, through (3,0)
y = -1/2 x + b
0 = -1/2(3) + b
0 = -1.5 + b
0 + 1.5 = b
1.5 = b
y = -1/2 x + 1.5
Step-by-step explanation:
(1)
AX is bisector of 
(2)
(Remaining angle of quadrilateral)
is a rectangle.
(adjacent sides of a rectangle)
is a square.
Hence proved.
I’m not sure what the negative fours are at the end of your problem are for, but the slope of the line passing through those points is 4.
The line itself is y = 4x - 11
Answer:
4
Step-by-step explanation:
Two ways to solve this - either divide 140 by 35 (140/35 = 4)
or keep adding 35 until you reach 140: 35+35+35+35 = 140
