24 Lb for Is A Better Deal But 22 LB Is the Lowest by 2 Cents
Answer:
The form is y=mx+b where m is the slope and b is the y-intercept
1)
y=4/3x-5
2)
y=-3/2x+4
y-intercept is (0,4)
4-1/0-2=3/-2=-3/2
3)
y=-2/3x
y-intercept is (0,0)
0-(-2)/0-3=2/-3=-2/3
4)
y=2x-1
9-3/5-2=6/3=2
y-9=2(x-5)
y=2x-10+9
y=2x-1
