1) You know that a is 4/5 of b. This can be written as:
.
To find what b is equal to, multiply both sides by 5/4:
.
A is 5/4 B.
2) You know that a is 1/5 smaller than b. This can be written as:
.
To find b, just add 1/5 to both sides:
.
B is 1/5 bigger than a.

Step-by-step explanation:
To graph, use y=mx+b as a guide where m is the slope and b is the y-intercept.
y=-3x-4
Start at -4 on the y-axis. Plot a point. This is the y-intercept b. From this point count down 3 units and 1 unit to the right. Plot this point and connect.
y=3/4x +2
Start at 2 on the y-axis. Plot a point. This is the y-intercept b. From this point count up 3 units and 4 units to the right. Plot this point and connect.
