Question

in the equation y=3x-4 a point on the line is

Answer 1

well if x is 1,
\[y=3x-4\]
becomes
\[y=3-4\]\[y=-1\]
so (1,-1) is a point on the line

Answer 2

or alternatively if x is 2
\[y=3x-4\]becomes
\[y=6-4\]\[y=2\]
so (2,2) is also a point on the line

Answer 3

in fact there are an infinite number of points , each value of x will give a value for y,

Answer 4

if you set x= 0
you'll find the y intercept
