y = 3x + 2 and y =4x - 3
for y = 3x + 2
when x = 0
This means to find y put x = 0
y = 3(0) + 2
y = 0 + 2
y = 2
to find x put y = 0
from the equation
y = 3x + 2
0 = 3x + 2
make 3x the subject of the formula
0 - 2 = 3x
-2 = 3x
divide both sides by 3
-2/3 = 3x/3
-2/3 = x
the sloutions for the y = 3x +2 are
(0, 2) and (-2/3, 0)
for the second equation
y = 4x - 3
to find y let x = 0
y = 4(0) - 3
y = 0 - 3
y = -3
to find x let y = 0
0 = 4x - 3
make 4x the subject of the formula
0 + 3 = 4x
3 = 4x
divide both sides by 4
3/4 = 4x / 4
x = 3/4
The solutions fro y = 4x - 3
(0, -3) and (3/4, 0)
