PLS HELP ASAP

How to graph these following equations?
t=4x
t=4y
b=70x+55y
a=x+y

Answer 1

1) t= 4x

for x = 0, t = 0

x = 1, t = 4

x = 2, t = 8 ......

2) t = 4y

for y = 0, t = 0

y = 1, t = 4

y = 2, t = 8 ....

3) b= 70x + 55y

let b= 1

for x= 1 & y= -69/55

for y = 1 & x= -54/70

4) a= x+y

let a = 1

for x = 1 , y = 0

for y = 1, x = 0
