Answer: -2.25
9x+4y=8
4y=-9x+8
y= -9/4x+8/4
y=-2.25x+2
I hope this is good enough:
Answer:
Put a point at (-7,0) and another at (0,-2)
Step-by-step explanation:
2x+7y=-14
Plug in 0
2(0)+7y= -14
7y=-14
y=-2
same thing for x
2x+7(0)=-14
x=-7
1 feet = 12 inches
3.5 feet = x inches
Cross multiply
12(3.5) = 1x
x = 42 inches
